A ball of mass 1 kg is dropped from a tower. Find power of gravitational force at time `t=2s`. Take `g=10m//s^(2).

A body of mass 10 kg is dropped to the ground from a height of 10 metres. The work done by the gravitational force is (g=9.8m//sec^(2))

A body of mass 10 kg is dropped to the ground from a height of 10 metres. The work done by the gravitational force is (g=9.8m//sec^(2))

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 of mass 50 g is dropped from a height of 20 m. A boy on the ground hits the ball vertically upwards with a bat with an average force of 200 N, so that it attains a vertical height of 45 m. The time for which the ball remains in contact with the bat is [Take g=10m//s^(2)]

A ball of mass 50 g is dropped from a height of 20 m. A boy on the ground hits the ball vertically upwards with a bat with an average force of 200 N, so that it attains a vertical height of 45 m. The time for which the ball remains in contact with the bat is [Take g=10m//s^(2)]
