When a cricket ball is thrown vertically upwards, it reaches a maximum height of 5 metres. (a) What was the initial speed of the ball ? (b) How much time is taken by the ball to reach the highest point ? (g=10 m s^(-2))

A ball is thrown from the top of a 60m high tower with velocity 20sqrt(2)m//s at 45^(@) elevation.Find the radius of curvature of path at highest point. ( g=10m//s^(2) )

A boy throws a ball upward with velocity v_(0)=20m//s . The wind imparts a horizontal acceleration of 4m//s^(2) to the left. The angle theta at which the ball must be thrown so that the ball returns to the boy's hand is : (g=10ms^(-2))

A ball of mass 400 gm is dropped from a height of 5 m. A boy on the ground hits the ball vertically upwards with a bat with an average force of 100 newton so that it attains a vertical velocity of 20 m/s. The time for which the ball remains in contact with the bat is (g=10m//s^(2))
