An iron ball of mass m=50 g falls from a height of `(h_1)=5m` and rises upto `h_(2)=3.2m` after colliding with the horizontal surface. If the time of contant of the glass half is `Delta t=0.02s`, find the average contact force exerted on the ball by the horizontal surface.

A ball of mass = 100 gm is released fom a height h_(1)=2.5m above the ground level and then rebounds to a height h_(2)=0.625 m . The time of contact of the ball with the ground is Delta t = 0.01 sec. Find the impulsive (impact) force offered by the ball on the ground.

A rubber ball of mass 0.05 kg falls from a height of 1 m and rebounds to a height of 0.5 m. Find the average force when their contact was 0.1 sec.

A steel ball of mass 0.5 kg is dropped from a height of 4 m on to a horizontal heavy steel slab. The collision is elastic and the ball rebounds to its original height. If the ball is in contact with the slab for 0.002 s, find the average reaction force on the ball during impact.

A rubber ball of mass 50g falls from a height of 100cm and rebounds to a height of 50cm Find the impulse and average force between the ball and the ground, if time of contact is 0.1s .

A rubber ball of mass 50 g falls from a height of 5m and rebounds to a height of 1.25 m. Find the impulse and the average force between the ball and the ground if the time for which they are in contact was 0.1s

A rubber ball of mass 50 g falls from a height of 5m and rebounds to a height of 1.25 m. Find the impulse and the average force between the ball and the ground if the time for which they are in contact was 0.1s

A ball of mass 50 g falls from a height of 10 m and rebounds to a height of 5 m.Find the impulse and average force between the ball and ground if both were in contact for 0.1 second.

A steel ball of mass w=50gm falls from height h=1 m on the horizontal surface of a massive slab. Find the cumulative momentum imparted to the slab by the ball after numerous bounces, if the coefficient of restitution between the ball and the slab is e = 0.8.
