A 5 Kg bowling ball is thrown at a stationary 1.6 Kg bowling pin at 5 m/s. If the final velocity of the ball is 2.5 m/s. The final velicoty of the bowling pin is _____m/s. ​

Answers

Answer: hope this helps

Explanation:

If the final velocity of the ball is 2.5 m/s, the final velocity of the bowling pin is 7.8125 m/s. ​

What is principle of conservation of momentum?

According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.

According to the principle of momentum conservation,  total momentum of an system remains conserved.

Total initial momentum = total final momentum

5 kg × 5 m/s + 1.6 kg × 0 m/s = 5 kg × 2.5 m/s + 1.6 kg × v

1.6 kg × v  = 5 kg × 5 m/s -  5 kg × 2.5 m/s

v = (5 kg /1.6 kg) (5 m/s - 2.5 m/s)

= 7.8125 m/s

Hence, If the final velocity of the ball is 2.5 m/s, the final velocity of the bowling pin is 7.8125 m/s. ​

Explanation:

What is the netforce?

Answers

Answer:

6 Newtons to the left.

Explanation:

We can convert  this into a generic algebra equation by giving directions positive and negative values.

The 6 will be positive, and the 10 and 2 will be negative.

Add 10 and 2 to have 12.

6-12 = -6.

Therefore you have 6 newtons to the left (negative).

Take the force towards the right as positive (+6N) and towards the left as negative (-12N)
Add both as net force is the sum of all forces acting on an object
6N+(-12N)= -6N

From base camp, a park ranger drives 27 meters at 32 degrees East of North, then 40 meters at 58 degrees West of North, and finally 39 meters directly West in an attempt to rescue a lost hiker.

Answers

Answer:

R = 73.34 m,   θ = 37º North of West

Explanation:

In this exercise you are asked to find the distance traveled.

The best way to do this is with a Cartesian coordinate system, let's use a system where the x axis coincides with the West - East direction), to decompose the trajectories

First trajectory

distance d₁ = 27 m

Direction 32 East of North, this angle is measured from the vertical direction (y-axis)

           cos 32 = y₁ / d₁

           sin 32 = x₁ / d₁

           y₁ = d₁ cos 32

           x₁ = d₁ sin 32

           y₁ = 27 cos 32 = 22.90 m

           x₁ =  27 sin 32 = 14.31 m

second trajectories

distance d2 = 40 m

direction 58 West from North, the angle is measured with respect to the y axis, towards the negative side of the x axis

            cos 58 = y₂ / d₂

            sin 32 = x₂ / d₂

            y₂ = d₂ cos58

            x₂ = d₂ sin 58

            y₂ = 40 cos 58 = 21.20 m

            x₂ = 40 sin 58 = -33.92 m

The negative sign of the x coordinate is due to the fact that the displacement is towards the West (negative of the x axis)

third trajectory

distance d₃ = 39 m

West direction, negative part of x-axis

             x₃ = - 39 m

the total distance is

            = x₁ + x₂ + x₃

            X_{total}l = 14.30 - 33.92 -39

            X_{total}X_total = -58.6 m

           

            Y_{total} = y₁ + y₂

             Y_{total}= 22.90 + 21.20

             Y_{total} = 44.1 m

we give the result in the form of module and angle

we use the Pythagorean theorem

              R = [tex]\sqrt{X_{total}^2 + Y_{total}^2 }[/tex]

              R =\sqrt58.6^2 + 44.1^2 }

              R = 73.34 m

we use trigonometry

               tan θ =

               θ = tan⁻¹ \frac{  Y_{total} }{ X_{total} }

θ = tan⁻¹ \frac{ 44.1 }{ 58.6 } (44.1 / 58.6)

            θ = -37º

this angle is in the second quadrant, given in the form of cardinal coordinates is

              θ = 37º North of West

Dominique and her sister are practicing their basketball skills at the park. If both Dominique and her sister both throw their basketballs at the same time and they hit each other. What would happen to their basketballs? a) Only the basketball's speed would be changed b) Only the basketball's directions would be changed c) Both the basketball's speed and direction would change d) Neither the basketball's speed nor direction would change

Answers

Answer:

Option C, Both the basketball's speed and direction would change

Explanation:

When two objects travelling with certain speed interact with each their internal forces changes and hence their motion changes simultaneously.

In general cases it is said that momentum is conserved. Momentum is nothing but just the product of mass and velocity.

As the motion of the football changes, then momentum also changes. Since mass is a constant value, it is the velocity of the football that changes.

Hence, both speed and direction of both the football changes.

Option C is correct

A 2500-kg car is being pushed up a hill at an angle of 35 degrees. Determine the gravitational

force pulling down on the car if it is accelerating up the hill at a rate of 5 m/s/s.

Answers

Answer:

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

Explanation:

For this exercise we will use Newton's second law, let's set a reference system where the x axis is parallel to the plane, in the adjoint we can see the forces in the system.

           sin  35 = Wₓ / W

            cos 35 = W_y / W

            Wₓ = W sin 35

            W_y = W cos 35

            Wₓ = 2500 9.8 sin 35

             Wₓ = 14052.6 N

let's write the equations for each axis

and

Y axis  

       N-W_y = 0

       N = W_y

X axis  

       F -Wₓ = m a

       F = Wₓ + m a = mg sin 35 + m a

       F = m (a + g sin 35)

   

let's calculate

       F = 2500 (5 + 9.8 sin 35)

       F = 26552.6 N

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

Physicists often use a different unit of energy, the electron volt, when dealing with energies at the atomic level. One electron volt, abbreviated eV, is defined as the amount of kinetic energy gained by an electron upon accelerating through a 1.0 V potential difference.

a) what is 1.0 electron volt in joules?

b) what is the speed of a proton with 5000 eV of kinetic energy?

Answers

Answer:

a)  E = 1.06 10⁻¹⁹ J,     b)   v = 9.78 10⁵ m / s

Explanation:

The physical magnitudes can be given in several units, but in general all must be reduced to the same system in a given exercise, the most used system is the international (SI)

           1 eV =q V=  1.6 10⁻¹⁹ J

let's reduce the quantities requested

a) E = 1.0 eV to Joule

           E = 1.0 eV (1.6 10⁻¹⁹ J / 1 eV)

           E = 1.06 10⁻¹⁹ J

b) the kinetic energy is given by

           K = ½ m v²

           v = [tex]\sqrt{\frac{2K}{m} }[/tex]

the mass of the proton is

          m = 1,673 10⁻²⁷ kg

let's reduce the energy to the SI system

           E = 5000 ev (1.6 10-19 J / 1 eV) = 8000 10⁻¹⁹ J

let's calculate

           v = [tex]\sqrt{ \frac{2 \ 8000 \ 10^{-19}}{1.673 \ 10^{-27} } }[/tex]

           v = [tex]\sqrt{ 95.637 \ 10^{10} }[/tex]

           v = 9.78 10⁵ m / s

Hari drag a load of 60 kg along a distance of 12 metre what amount of work does he do also mention the type of work​

Answers

Answer:

W = 7056  J

Explanation:

Given that,

Mass of a load, m = 60 kg

Distance moved, d = 12 m

We need to find the amount of work. The work done by an object is given by :

W = Fd

So,

W = mg×d

W = 60 kg × 9.8 m/s²×12 m

W = 7056  J

So, the amount of work done is 7056  J.

3. Why is static electricity not useful as a power

source?

A. Because electrons aren't transferred in bursts of

static electricity

B. Because all energy is released at once in static

electricity

C. Because static electricity is not a real form of

electricity

D. Because static electricity only occurs in lightning

Answers

The answer is B, because all energy is released at once in static electricity.

There’s a quizlet that mentions these questions, if you are having trouble. I’d suggest to give them a look.

Static electricity is not useful as a power source primarily because it releases all of its energy at once rather than providing a continuous and controlled flow of electrical energy. The correct answer is B.

When static electricity is discharged, such as in a spark or a sudden discharge of stored charge, it happens in a rapid and uncontrolled manner, resulting in a brief burst of energy rather than a steady and sustained flow.

Power sources typically require a continuous and controllable flow of electrical energy to be useful for various applications. Static electricity, in its nature, does not provide this continuous flow but instead releases energy in an instantaneous manner. Therefore, it is not suitable for most practical power needs and applications.

Option A is not correct because electrons can be transferred in bursts of static electricity. Option C is not correct because static electricity is a real form of electricity, even though it has unique characteristics. Option D is not correct because static electricity can occur in various circumstances, not just in lightning.

Therefore, Static electricity is not useful as a power source primarily because it releases all of its energy at once rather than providing a continuous and controlled flow of electrical energy. The correct answer is B.
