A ball is dropped from a height of 90 m on a floor. At each collision with the floor, the ball loses one tenth of its speed. Plot the speed-time graph of its motion between t = 0 to 12 s.

An inelastic ball is dropped from a height of 100 m.Due to earth 20 % of its energy is lost.to what height will the ball rise?

A ball is dropped from a height of 1 m.If coefficient of restitution between surface and ball is 0.6 ,the ball rebounds to a height of :

A ball dropped from a height 'h' reaches the ground in time 'T'. What is its height from the ground at time T/2 ?

An object is relased from a height. Find its speed at t = 1s

An object is relased from a height. Find its speed at t = 3s

An object is relased from a height. Find its speed at t = 2 s

A ball is gently dropped from a height of 20 m. If its velocity increases uniformly at the rate of 10 ms^(-2) , with what velocity it will strike the ground ? After What time will it strike the ground ?

A rain drop of radius 2 mm falls from a height of 500 nr above the ground. It falls with decreasing acceleration (due to viscous resistance of the air) until at half its original height, it attains its maximum (terminal) speed, and moves with uniform speed thereafter. What is the work done by the gravitational force on the drop in the first and second half of its journey ? What is the work done by the resistive force in the entire journey if its speed on reaching the ground is 10 m s^-1 ?
