A Hard Rubber Ball Is Dropped From Rest

It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height.

A hard rubber ball is dropped from rest.

Assume the heavier ball reaches the floor first and bounces elastically. When the balls are released the lighter ball with mass m is directly above the heavier ball with mass m. 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. Almost everybody at some point in their lives has bounced a rubber ball against the wall or floor and observed its motion.

On the way down v1y v0y 2g y v1y 2 9 8 2 0 6 26 ms 1 ball moving down 22. Explain the answer. A hard rubber ball is dropped from rest. Thus when the balls collide the ball of mass m is moving.

A rubber ball is dropped from rest at a fixed height. Energy was required to deform the ball s shape during the collision with the floor. 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.

It falls to the floor and bounces back up to almost its initial height. A rubber ball is dropped from rest at a fixed height. A motion detector is mounted on the ceiling directly above the ball facing down. 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.

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. So in this example the positive direction the away from the detector direction is downward. A rubber ball with a mass of 0 160 kg is dropped from rest.

How high does the ball bounce. From what height was the ball dropped if the magnitude of the ball s momentum is 0 760 kg. What is the best way to explain the loss of kinetic energy of the ball during the collision.
