A ball has a mass of 5 kg. It falls down 2 meters (h= 2) and hits a spring (that has no mass) with a constant of k= 300 N/m.
The height where the ball lands on top of the spring is at y=0, and the spring is at rest. We only want to know the ball's motion when it comes into contact with the spring.
1. What is the kinetic energy of the ball at height, y=0. Please draw a FBD (free body diagram) for the ball.
2. At what height (y- value) is the velocity of the ball 0? At what height is the acceleration 0?
3. At what height is their a max net force upon the ball?

A) A mass of 2.9 kg is dropped from a height of 4.07 meters above a vertical spring anchored at its lower end to the floor. If the spring constant is 25 N/cm, how far, to the nearest tenth of a cm, is the spring compressed? B) If the top of the spring in the preceding problem is 1.99 meters above the ground when the mass is released, what is the ball's kinetic energy, to the nearest Joule, just before...

A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released from rest. It travels over a horizontal surface, up an incline which has a height (not length) of 5 meters, and then travels over another horizontal surface. At the end of that surface is another spring with the same spring constant. The mass hits the second spring and eventually stops after compressing it 2.3 meters. What is the elastic potential energy of the second...

A 1-kg ball in the air has an initial velocity vo = [ 10 ] i + [ -20 ] j m/s. It falls for a total time of 1 s. Assume that positive x-values are to the right and positive y-values are upward. What is the initial kinetic energy Ki of the ball? J Remember that the initial kinetic energy Ki = pi2/2m. To find the magnitude of the resultant momentum we must use the pythagorean theorem on the...

A ball of mass 0.20 kg is fired with velocity 120 m/s into the barrel of a spring gun of mass 2.0 kg initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. No energy is lost to friction. What fraction of the ball's initial kinetic energy is stored in the spring?
