A ball of mass 1 kg is dropped from height 9.8 m, strikes with ground and rebounds at height 4.9 m, if the time of contact between ball and ground is 0.1 s then find impulse and average force acting on ball.

A ball of mass 0.15kg is dropped from a height 10m strikes the ground and rebounds to the same height. The magnitude of impulse imparted to the ball is ( g = 10 m/s^2 ) nearly:

A ball is dropped from a height of 5 m, if it rebound upto height of 1.8 m, then the ratio of velocities of the ball after and before rebound is :

A ball is dropped from a height of 5 m, if it rebound upto height of 1.8 m, then the ratio of velocities of the ball after and before rebound is :

A ball of mass 10 gm dropped from a height of 5m hits the floor and rebounds to a height of 1.25m. If the ball is in contact with the ground for 0.1s, the force exerted by the ground on the ball is (g=10 m//s^(2))

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 ball is dropped from height 5m. The time after which ball stops rebounding if coefficient of restitution between ball and ground e=1//2 , is

A ball is dropped from height 5m. The time after which ball stops rebounding if coefficient of restitution between ball and ground e=1//2 , is
