A Hard Rubber Ball Is Dropped From Rest

A rubber ball with a mass of 0 160 kg is dropped from rest.

A hard rubber ball is dropped from rest.

It falls to the floor and bounces back up to almost its initial height. Energy was required to deform the ball s shape during the collision with the floor. When the balls are released the lighter ball with mass m is directly above the heavier ball with mass m. What is the best way to explain the loss of kinetic energy of the ball during the collision.

At what height above the ground do the balls collide. It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height. How high does the ball bounce. A motion detector is mounted on the ceiling directly above the ball facing down.

On the way down v1y v0y 2g y v1y 2 9 8 2 0 6 26 ms 1 ball moving down 22. Two small rubber balls are dropped from rest at a height h above a hard floor. A rubber ball is shot straight up from the ground with speed v0. When a rubber ball dropped from rest bounces off the floor its direction of motion is reversed becaue a energy of the ball is conserved b momentum of the ball c the floor exerts a force on the ball that stops its fall and then drives it upward d the floor is in the way and the ball has to keep moving e non of the above.

Assume the heavier ball reaches the floor first and bounces elastically. From what height was the ball dropped if the magnitude of the ball s momentum is 0 760 kg. Thus when the balls collide the ball of mass m is moving. It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height.

So in this example the positive direction the away from the detector direction is downward. Explain the answer. A 100 g rubber ball is dropped from a height of 2 0 m onto a hard floor with the force exerted by the floor on the ball shown in the figure. A rubber ball is dropped from rest at a fixed height.

What is the best way to explain the loss of kinetic energy of the ball during the collision. Simultaneously a second rubber ball at height h directly above the first ball is dropped from rest. A rubber ball is dropped from rest at a fixed height.
