Atoy rocket engine is securely fastened to a large puck that can glide with negligible friction over a horizontal surface, taken as the xy plane. the 4.20-kg puck has a velocity of 1.60î m/s at one instant. eight seconds later, its velocity is (6.00î + 4.0ĵ) m/s. (a) assuming the rocket engine exerts a constant horizontal force, find the components of the force.
