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 (– 1) m/s. At a particular instant when the line OA makes an angle of 45owith the x-axis, a ball is thrown along the surface from the origin O. Its velocity makes an anglewith the x-axis and it hits the trolley.Find the speed of the ball with respect to the surface, it= 4/3.
