After you let go of a bowling ball, is there a force pushing it so that it keeps moving
forward? Explain.

Answers

Answer 1

Explanation:

No, the ball keeps moving forward due its momentum.

A net force causes an object to accelerate, which means it speeds up, slows down, or changes direction.  A bowling ball does not speed up after you let go, so there is no forward force.

A 3.00 kg mass is traveling at an initial speed of 25.0 m/s. What is the
magnitude of the force required to bring the mass to rest in a distance of 62.5m?

Answers

Answer:

The magnitude of the force required to bring the mass to rest is 15 N.

Explanation:

Given;

mass, m = 3 .00 kg

initial speed of the mass, u = 25 m/s

distance traveled by the mass, d = 62.5 m

The acceleration of the mass is given as;

v² = u² + 2ad

at the maximum distance of 62.5 m, the final velocity of the mass = 0

0 = u² + 2ad

-2ad = u²

-a = u²/2d

-a = (25)² / (2 x 62.5)

-a = 5

a = -5 m/s²

the magnitude of the acceleration = 5 m/s²

Apply Newton's second law of motion;

F = ma

F = 3 x 5

F = 15 N

Therefore, the magnitude of the force required to bring the mass to rest is 15 N.

Explanation:

A student walks to the right 25-m along the 800 hall in 15-s. They turn around and walk 15-m to the left in 8.0-s. Calculate the average speed and the average velocity

Answers

Answer:

Explanation:

Total distance covered  = 25 + 15 = 40 m

Total time = 15 + 8 = 23 s

Average speed = total distance covered / total time

= 40 / 23

= 1.74 m / s

Total displacement = 25 - 15 = 10 m

Total time = 15 + 8 = 23 s

Average velocity = total displacement / total time

= 10 / 23

= .434 m / s to the right .

The average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left).

Given:

Distance to the right = 25 m

Time taken to the right = 15 s

Distance to the left = 15 m

Time is taken to the left = 8.0 s

To calculate the average speed and average velocity, we need to use the following formulas:

Average speed = Total distance traveled ÷ Total time taken

Average velocity = Displacement ÷ Total time taken

Calculate the total distance traveled:

Total distance = Distance to the right + Distance to the left

Total distance = 25 + 15 = 40 m

Calculate the total time taken:

Total time = Time taken to the right + Time taken to the left

Total time = 15 + 8.0 = 23 s

Calculate the average speed:

Average speed = Total distance ÷ Total time

Average speed = 40 ÷ 23 = 1.74 m/s

Calculate the displacement:

Displacement = Final position - Initial position

Displacement = (-15 ) - 25  = -40 m

Calculate the average velocity:

Average velocity = Displacement ÷ Total time

Average velocity = -40 ÷ 23  ≈ -1.74 m/s

So, the average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left). The negative sign in the average velocity indicates that the student's net direction is to the left.

If a bullet with an acceleration of 1.5 m/s2 takes 2 seconds to leave the muzzle of a rifle (starts at rest), what was the length of the rifles barrel?

Answers

Answer:

The length is   [tex]D  =3 \  m  [/tex]

Explanation:

The  velocity of the bullet is mathematically evaluated as

      [tex]v  =  a * t [/tex]

=>   [tex]v  = 1.5 * 2 [/tex]

=>    [tex]v  = 3 \  m/s  [/tex]    

Now from kinematic equation

       [tex]v^2  =  u^2 + 2* a  *  D[/tex]

Here  D is the length of the barrel  and  u =  0 m/s

So

     [tex]3^2  =  0 + 2* 1.5  *  D[/tex]

     [tex]D  = \frac{9}{3} [/tex]

      [tex]D  =3 \  m  [/tex]

A 0,34-kg volleyball is flying west at 1,98 m/s when it strikes a stationary 0,60-kg basketball dead centre. The volleyball rebounds east at 0,79 m/s. What will be the velocity of the basketball immediately after impact? Choose the east direction as positive.

Answers

Explanation:

use the law of conservation of momentum

M1U1+M2U2=M1V1+M2V2

m-mass

u-initial velocity

v-final velocity

1-volleyball

2-basket ball dead center

so using the above formula

0.34×1.98+0.64×0=0.34×0.79+0.64×V2

to get

0.6732+0 = 0.2686+0.64V2

0.4046=0.64V2

divide both sides by 0.64 to get V2 which is the final velocity of basketball

0.6322m/s=V2

The final velocity of the basketball after the impact is 1.643 m/s west.

The given parameters;

mass of the volleyball, m = 0.34 kginitial velocity of the volleyball, u₁ = 1.98 m/smass of the stationary basketball, m₂ = 0.6 kgfinal velocity of the volleyball, v₁ = 0.79 m/s

The final velocity of the basketball after the impact is calculated by applying the principle of conservation of linear momentum;

m₁u₁  +  m₂u₂  =  m₁v₁   +  m₂v₂

0.34(-1.98) + 0.6(0) = 0.79(0.34) + 0.6(v₂)

-0.673 = 0.316 + 0.6v₂

-0.989 = 0.6v₂

[tex]v_2 = \frac{- 0.989}{0.6} \\\\v_2 = -1.643 \ m/s\\\\v_2 = 1.643 \ m/s \ west[/tex]

Thus, the final velocity of the basketball after the impact is 1.643 m/s west.

A soccer player kicks a ball horizontally at 25.0 m/s from a bridge, and the ball hits
the ground after 1.5 s.
2
How high is the bridge?

Answers

Answer: 11.025 meters.

Explanation:

Ok, we know that the initial velocity is only horizontal, so it does not affect the vertical problem.

Looking only at the vertical problem (because we want to know how high is the bridge) we have that:

The acceleration is the gravitational acceleration, g = 9.8m/s^2

A(t) = -9.8m/s^2

Where the negative sign is because this acceleration is downwards.

For the vertical velocity we integrate over time, as we do not have an initial vertical velocity, there is no constant of integration.

V(t) = (-9.8m/s^2)*t

For the position we integrate over time again, here the constant of integration is the initial vertical position, H, that is the height of the bridge.

P(t) = 0.5* (-9.8m/s^2)*t^2 + H.

Now we know that the ball hits the ground 1.5s after it was kicked, then:

p(1.5s) = 0m

With that we can find the value of H.

0 = 0.5* (-9.8m/s^2)*(1.5s)^2 + H.

H = 0.5*(9.8m/s^2)*(1.5s)^2 = 11.025m

Answer:

Saturn

Explanation:

W = mg

150 N = m (9.8 m/s²)

c. 171m/s
d. 9.8 m/s
e. 17.5 m/s

Answers

Given :

Height from which rock is dropped, h = 17.5 m.

Initial velocity, u = 0 m/s.

To Find :

Speed does the rock strike the water.

Solution :

We know, by equation of motion :

[tex]v^2-u^2=2as[/tex]      ......( 1 )

Here , a = g = 9.8 m/s² ( Acceleration due to gravity )

Putting all given values in 1 , we get :

[tex]v^2-u^2=2as\\\\v=\sqrt{2gh}\\\\v=\sqrt{2\times 9.8\times 17.5}\ m/s\\\\v=18.5\ m/s[/tex]

Therefore, speed with rock strike the water is 18.5 m/s.

Hence, this is the required solution.
