A Hard Rubber Ball Is Dropped From Rest

A rubber ball is dropped from rest at a fixed height.

A hard rubber ball is dropped from rest.

At what height above the ground do the balls collide. From what height was the ball dropped if the magnitude of the ball s momentum is 0 760 kg. So in this example the positive direction the away from the detector direction is downward. What is the best way to explain the loss of kinetic energy of the ball during the collision.

Two small rubber balls are dropped from rest at a height h above a hard floor. 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. Normally we don t think about the physics of bouncing balls too much as it s fairly obvious what is happening the ball basically rebounds off a surface at a speed proportional to how fast it is thrown. 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. On the way down v1y v0y 2g y v1y 2 9 8 2 0 6 26 ms 1 ball moving down 22. A rubber ball with a mass of 0 160 kg is dropped from rest. A motion detector is mounted on the ceiling directly above the ball facing down.

It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height. When the balls are released the lighter ball with mass m is directly above the heavier ball with mass m. Thus when the balls collide the ball of mass m is moving. Energy was required to deform the ball s shape during the collision with the floor.

Explain the answer. 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 hard rubber ball is dropped from rest.

A rubber ball is shot straight up from the ground with speed v0. Simultaneously a second rubber ball at height h directly above the first ball is dropped from rest. 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.
