3. A 180 g hockey puck slides on (frictionless) ice at a speed of 2 m/s. It then slides onto a carpet, which exerts a constant frictional force Ff = 0.7 N in the direction opposite the puck's direction of motion. (a) Draw two free body diagrams: one when the puck is on the ice, and the other when the puck is on the carpet. Include any forces acting in the vertical direction (perpendicular to the ice or carpet) and any acting in the horizontal direction (parallel to the ice or carpet). (b) Do you expect the velocity of the puck to be constant on the ice? How about on the carpet? Why or why not? (c) How far does the puck travel on the carpet before coming to a stop?
