Question

A cart is moving along +ve x-direction with a speed of 4 m/s. A person on the cart throws a stone with a velocity of 6 m/s w.r.t. himself. In the frame of reference of the cart the stone is thrown in the y-z plane making an angle of 30° with the vertical z-axis. Then w.r.t. an observer on the ground :
