It falls to the floor and bounces back up to almost its initial height.
A hard rubber ball is dropped from rest.
At what height above the ground do the balls collide.
Assume the heavier ball reaches the floor first and bounces elastically.
It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height.
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.
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 with a mass of 0 160 kg is dropped from rest.
Explain the answer.
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.
Simultaneously a second rubber ball at height h directly above the first ball is dropped from rest.
So in this example the positive direction the away from the detector direction is downward.
On the way down v1y v0y 2g y v1y 2 9 8 2 0 6 26 ms 1 ball moving down 22.
Thus when the balls collide the ball of mass m is moving.
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.
What is the best way to explain the loss of kinetic energy of the ball during the collision.
A rubber ball is dropped from rest at a fixed height.
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.
When the balls are released the lighter ball with mass m is directly above the heavier ball with mass m.
A hard rubber ball 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.
It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height.
A motion detector is mounted on the ceiling directly above the ball facing down.
