A Hard Rubber Ball Is Dropped From Rest

A hard rubber ball is dropped from rest.

A hard rubber ball is dropped from rest.

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. Thus when the balls collide the ball of mass m is moving. Two small rubber balls are dropped from rest at a height h above a hard floor. Almost everybody at some point in their lives has bounced a rubber ball against the wall or floor and observed its motion.

A rubber ball is shot straight up from the ground with speed v0. At what height above the ground do the balls collide. 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.

How high does the ball bounce. 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. What is the best way to explain the loss of kinetic energy of the ball during the collision.

When the balls are released the lighter ball with mass m is directly above the heavier ball with mass m. 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 with a mass of 0 160 kg is dropped from rest. It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height.

A rubber ball is dropped from rest at a fixed height. 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. So in this example the positive direction the away from the detector direction is downward. Assume the heavier ball reaches the floor first and bounces elastically.

Energy was required to deform the ball s shape during the collision with the floor. It falls to the floor and bounces back up to almost its initial height. On the way down v1y v0y 2g y v1y 2 9 8 2 0 6 26 ms 1 ball moving down 22.
