A ball thrown vertically upward returns to its starting point in 4 s. Find its initial speed.

A ball of mass m is thrown vertically up with an initial velocity so as to reach a height h.The correct statement is :

A ball is projected vertically upwards with a certain initial speed. Another ball of the same mass is projected at an angle of 60^(@) with the vertical with the same initial speed. At highest points of their journey, the ratio of their potential energies will be

A ball is projected vertically upwards with a certain initial speed. Another ball of the same mass is projected at an angle of 60^(@) with the vertical with the same initial speed. At highest points of their journey, the ratio of their potential energies will be

A ball thrown vertically upwards with an initial velocity of 1.4 m//s. The total displcement of the ball is

A ball is thrown downwards with a speed of 20 m s^(-1) , from the top of a building 150 m high and simultaneously another ball is thrown vertically upwards with a speed of 30 m s^(-1) from the foot to the building . Find the time after which both the balls will meet. (g=10 m s^(-2)) .
