A ball is dropped from the height of 50m. At a distance of 40m from the foot of perpendicular point 'P'is observing the ball. Calculate the angular velocity (in rad/sec) of the point 'P' at t = 2sec.

A ball is dropped from height 10 m . Ball is embedded in sand 1 m and stops, then

A ball is dropped from a height h on to a floor . If the cofficient of restitution is e, calculate the height the ball first rebounds ?

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 on a floor from a height of 2.0m After the collision it rises up to a height of 1.5m . Assume that 40% of the mechanical energy lost goes as thermal energy into the ball. Calculate the rise in the temperature of the ball in the collision heat capacity of the ball is 800J K^(-1)
