After a 0 300 kg rubber ball is dropped from a height of 1 75 m it bounces off a concrete floor and rebounds to a height of 1 50 m.
A ball is dropped 1 m to the floor.
If the specific heat capacity of the ball is 8 0 0 j k then the rise in temperature of the ball during collision is take g 1 0 m s 2.
A rubber ball with a mass 0 20 kg is dropped vertically from a height of 1 5 m above the floor.
A calculate its velocity just before it strikes the floor.
The ball rebounds straight upward to a height of 0 7 m.
The ball bounces off of the floor and during the bounce 0 60 j of energy is dissipated.
Calculate the average force the floor exerts on the ball.
Assuming that 2 0 of mechanical energy is lost in the form of thermal energy.
While the magnitude and the direction of the impulse of the net force applied to the ball during the collision with the floor.
A ball is dropped on a floor from a height of 2 m.
Calculate the rise in the temperature of the ball in the collision.
A 0 5 kg ball is dropped from rest at a point 1 20 m above the floor.
A steel ball is dropped onto a hard floor from a height of 1 50 m and rebounds to a height of 1 45 m.
After the collision it rises upto a height of 1 m.
B calculate its velocity just after it leaves the floor on its way back up.
A determine the magnitude and direction of the impulse delivered to the ball by the floor.
B suppose the ball is in contact with the floor for 0 05 s.
A ball is dropped on the floor from a height of 10 m rebounds to a height of 2 5 m.
If the ball is in contact with the floor for 0 02 sec its average acceleration during contact is.
After the collision it rises up to a height of 1 5 m.
A ball is dropped on a floor from a height of 2 0 m.
