On a frictionless horizontal surface
A rocket is moving in a gravity free space with a constant acceleration of 2ms −2 , along + x direction (see figure). The length of a chamber inside the rocket is 4 m. A ball is thrown from the left end of the chamber in + x direction with a speed of 0.3ms −1 relative to the rocket. At the same time, another ball is thrown in -x direction with a speed of 0.2ms −1 from its right end relative to the rocket. The time in seconds when the two balls hit each other is

On a frictionless horizontal surface , assumed to be the x-y plane , a small trolley A is moving along a straight line parallel to the y-axis( see figure) with a constant velocity of sqrt 3 m/s . At a particular instant, when the line OA makes an angle of 45 degree with the x – axis, a ball is thrown along the surface from the origin O. Its velocity makes an angle phi with the x -axis and it hits the trolley . (a) The motion of the ball is observed from the frame of the trolley .
