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 3.60-kg puck has a velocity of 1.80i m/s at one instant. Eight seconds later, its velocity is (6.001 + 6.0j) m/s. (a) Assuming the rocket engine exerts a constant horizontal force, find the components of the force. i + i) N (b) Find its magnitude. IN Need Help?

When the angle of inclination of the plane is increased to 35.60, the toy duck begins to slide down the incline. Then, when the angle is decreased to 29.00, the speed of the toy duck is constant. What are the coefficients of static and kinetic friction between the toy duck and the incline? static kinetic
