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 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 trolley is accelerating down an incline of angle theta with acceleration g sintheta which of the following is correct (a is the angle made by the string with vertical)

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. .

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 particle is projected from a stationary trolley. After projection, the trolley moves with a velocity 2(sqrt15) m//s . For an observer on the trolley, the direction of the particle is as shown in the figure while for the observer on the ground, the ball rises vertically. The maximum height reached by the ball from the trolley is h meter. The value of h will be .......... .

A car is moving with velocity vec v_(c) towards north and a train is moving towards east with velocity vec v_(t) . Find the direction of relative velocity of car with respect to train.
