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 5.60-kg puck has a velocity of 2.00î m/s at one instant. Eight seconds later, its velocity is (6.00î + 6.0ĵ) m/s. (a) Assuming the rocket engine exerts a constant horizontal force, find the components of the force. (i+j) (b) Find its magnitude.
