A man throws a ball vertically upward and it rises through 20 cm and returns to his hands. What was the initial velocity (u) of the ball and for how much time (T) it remained in the air? (g = 10 m / s 2)

A thin, cylindrical rod ℓ = 2 4. 0 c m long with mass m = 1. 2 0 k g has a ball of diameter d = 8. 0 0 c m and mass M = 2. 0 0 k g attached to one end. The arrangement is originally vertical and stationary, with the ball at the top as shown in figure. The combination is free to pivot about the bottom end of the rod after being given a slight ...

A man throws balls into the air one after another. He always throws a ball when the previous one thrown has just reached the highest point. The height to which each ball rises, if he throws 5 balls per second is ( g = 10 m s − 2 ) :

The ball will maintain the same horizontal velocity as that of the person (or the compartment) at the time of throwing. If the ball appears to be moving backward to the person sitting in the compartment it means that speed of the train is increasing.

A man throws ball with the same speed vertically upwards one after the other at an interval of 2 seconds. What should be the speed of the throw so that more than two balls are in the sky at any time ? (G i v e n g = 9.8 m / s 2) Any speed less than 19.6 m / s; Only with speed 19.6 m / s; More than 19.6 m / s; At least 9.8 m / s

A man throws balls into the air one after another. He always throws a ball when the previous one thrown has just reached the highest point. The height to which each ball rises, if he throws 5 balls per second is (g = 10 m s − 2): 0.31 m; 0.42 m; 0.20 m; 0.53 m

A man is standing on a cart moving with a constant velocity 10 m/s, facing the direction of motion, throws a ball vertically upwards at 5 m/s with respect to himself. Then as observed from ground the ball will follow

A cricketer can throw a ball to a maximum horizontal distance of 100 m. With the same effort, he throws ...

The man is initially in the state of rest at a distance D from fixed vertical wall. He throws the ball towards the wall with a velocity V with respect to earth at-1-0. As a result of throwing, the man also starts moving backwards. The ball rebounds elastically from the wall. The man finally collects the ball. Assume friction to be absent.
