A player throws a ball upwards with an initial speed of `29.4 m s^-1` :- To what height does the ball rise and after how long does the ball return to the player’s hands ? (Take `g = 9.8 m s^-2` and neglect air resistance).

A player throws a ball upwards with an initial speed of 29.4 m s^-1 :- What is the direction of acceleration during the upward motion of the ball ?

A player throws a ball upwards with an initial speed of 29.4 m s^-1 :- What are the velocity and acceleration of the ball at the highest point of its motion ?

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can, equal to 49 m s^-1 . How much time does the ball take to return to his hands? If the lift starts moving up with a uniform speed of 5 m s^-1 and the boy again throws the ball up with the maximum speed he can, how long does the ball take to return to his hands ?

A 5 kg ball is trhown up with a speed of 10 m/s. What is the height to which it rises?

A body is thrown vertically upward with a velocity of 9.8 m//s^-1 Calculate the maximum height attained by the body. (g=9.8m//s^(2))

A cricket bowler releases tha ball in two different ways giving it horizontal velocity and a small downward velocity and the speed v_s at the time of release is the same. Both are relased at a height H from the ground. Which one will have greater speed when the ball hits the ground? Neglect air resistance.

A stone is thrown with an initial speed of 4.9 m/s from a bridge in vertically upward direction . It falls down in water after 2 sec. Find height of the bridge.
