At what time does the oscillator shown below first reach its Equilibrium Position?​

Answer:

187286 J

Explanation:

Lets work backwards. We are trying to find work, and are given kinematic variables. We know that the W = Fd, and since we already have d, all we need to find is F.

Using F = ma:

We know [tex]mg = W = 6900[/tex], and so solving for m, we get 704.082kg.

Now we can plug in the decelleration of the car with the mass in order to find the force against the car(by the brake).

[tex]F = 704.082*(-10) = -7040.82[/tex]

Now plugging this into W = Fd, we get:

[tex]W = (7040.82)*26.6 = 187286J[/tex]

This is just the magnitude, but if you wanted to find the sign of W, you would use the fact that the force is going in the opposite direction of the car, so work would be negative. However, this question asks only for the magnitude, so we ignore the final sign.

Answer:

   I = 2 A

Explanation:

Electric current is defined as the amount of face per unit of time

         I = Q / t

where Q is the charge and t is the time

let's reduce the time to the SI system

Complete Question:

Football player A has a mass of 110 kg, and he is running down the field with a velocity of 2 m/s. Football player B has a mass of 120 kg and is stationary. What is the total momentum after the collision?

Answer:

Total momentum = 220 Kgm/s.

Explanation:

Given the following data;

For footballer A

Mass, M1 = 110kg

Velocity, V1 = 2m/s

For footballer B

Mass, M1 = 120kg

Velocity, V1 = 0m/s since he's stationary.

To find the total momentum;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex] Momentum = mass * velocity [/tex]

a. To find the momentum of A;

[tex] Momentum \; A = 110 * 2 [/tex]

Momentum A = 220 Kgm/s.

b. To find the momentum of B;

[tex] Momentum \; B = 120 * 0 [/tex]

Momentum B = 0 Kgm/s.

c. To find the total momentum of the two persons;

[tex] Total \; momentum = Momentum \; A + Momentum \; B [/tex]

Substituting into the equation, we have;

[tex] Total \; momentum = 220 + 0 [/tex]

Total momentum = 220 Kgm/s.

The total momentum after the collision will be 220 Kgm/s.Momentum is equal to its mass multiplied by its velocity.

The measurement of mass in motion is called momentum. Momentum is equal to its mass multiplied by its velocity. Mathematically it is given as;

Momentum = Mass x Velocity

The given data in the problem is;

m₁ is the mass of player A= 110 kg

m₂  is the mass of player B= 120 kg

v₁ is the velocity of player A= 2m/s

v₂  is the velocity of player B=0m/s

P is the total momentum=?

The momentum of player A;

[tex]\rm P_A= m_A \times v_A \\\\ \rm P_A= 110 \times 2 \\\\ \rm P_A= 220 \ Kgm/sec[/tex]

The momentum of player B;

[tex]\rm P_B= m_B \times v_B \\\\ \rm P_B= 120 \times 0 \\\\ \rm P_B= 0 \ Kgm/sec[/tex]

The total momentum is given by;

Total momentum = momentum of the player A+ momentum of the player B

[tex]\rm P= P_A+P_B \\\\ \rm P= 220+0 \\\\ \rm P=220 \ m/sec[/tex]

Hence the total momentum after the collision will be 220 Kgm/s

Answer:

the momentum of the child is 337.5 kg.m/s

Explanation:

Given;

velocity of the wagon, v = 1.5 m/s

the combined mass of the child and the wagon, m = 225 kg

The momentum of the child is calculated as;

P = mv

substitute the given values of mass and velocity to determine the momentum,

P =  225 x 1.5

P = 337.5 kg.m/s

Therefore, the momentum of the child is 337.5 kg.m/s

Answer:

Force = 2802.8 Newton

Explanation:

Given the following data;

Mass = 130 lbs

But, 2.2 lbs = 1.0 kg

130 lbs to kg = 130 * 2.2 = 286 kg

Acceleration due to gravity = 9.8m/s²

To find the force in Newton;

Force = mass * acceleration due to gravity

Force = 286 * 9.8

Force = 2802.8 Newton

the height of the potential energy is 3,200 J

Explanation:

The computation of the kinetic energy is shown below:

Kinetic energy = 1 ÷ 2 × mass × velocity^2

= 1 ÷ 2 × 4 kg × 40 m/s^2

= 3,200 J

Hence the height of the potential energy is 3,200 J

Answer:

Uranus’ distance from the Sun is 2.88 billion km. The exact number is 2,876,679,082 km. Want that number in miles? Uranus’ distance from the Sun is 1.79 billion miles.

Explanation:

Uranus's average distance from the sun as multiple of earth's average distance from the sun is 19.2 AU.

According to Kepler's third law, the square of the period of revolution of the planets is equal to the cube of their mean distance from the sun in astronomical units.  

Using this law;

T^2 = r^3

T = period of revolution = 84 years

r = distance = ?

r = 3√T^2

r =  3√( 84)^2

r = 19.2 AU
