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 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 particle of mass m is moving with an acceleration a/3 towards left relative to the trolley car. An observer accelerates towards left with an acceleration of magnitude a/3. The trolley moves towards right with an acceleration a. Force experienced by particle (in ground frame of reference) is (xma)/3(+hati) . The value of 'x' is

A particle is projected from a stationary trolley. After projection, the trolly moves with velocity 2sqrt(15) m/s. for an observer on the trolley, the direction of the particle is as shown in the Fig. 5.121 while for the observer on the ground, the ball rises vertically. the maximum height reached by the abll from the trolley is h metre. The value of h will be:
