A toy 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 2.00-kg puck has a velocity of 2.00 I m/s at one instant. Eight seconds later, its velocity is (6 I + 18 j) m/s. Assuming the rocket engine exerts a constant horizontal force, find the components of the force.
