A boy projects a stone vertically perpendicular to the trolley car with a speed v. If the trolley car moves with a constant velocity u, the time of flight of the stone is :

A particle is projected form a trolley car with a velocity vecv . If the trolley can moves with an acceleration veca towards right, which of the following remain unchanged relative to both ground and trolley car?

A shell is projected from a gun with a muzzle velocity v .The gun is fitted with a trolley car at an angle theta as shown in the fig. If the trolley car is made to move with constant velocity v towards right, find the horizontal range of the shell relative to ground.

A stone is projected vertically upward from the top of a tower with a velocity u and strikes the bottom of the tower with a velocity 3u. The distance travelled by the stone is

A shell is projected from a gun with a muzzle velocity, u . The gun is fitted with a trolly car at an angle theta as shown in (Fig. 5.33). If the trolley car is made to move with constant velocity v towards right, find the (a) horizontal range of the shell relative to ground. (b) horizontal range of the shell relative to a person travelling with trolley. .
