FRQ — Incline, Pulley, and Friction A 4.20 kg block rests on a 31.0° incline and is connected by a light string over a low-friction pulley to a hanging 2.60 kg mass. The coefficient of kinetic friction between the block and incline is 0.220. The system is released from rest. The hanging mass moves downward and the block moves up the incline. (a) Draw complete free-body diagrams for both masses. Clearly define your coordinate systems. (b) Determine the acceleration of the system and the tension in the string. (c) After the hanging mass has descended 0.850 m, determine the speed of both masses. (d) Solve part (c) again using an energy approach and compare the result to the dynamics approach. (e) The string is cut after the block has moved 0.850 m up the incline. Determine how much farther the block travels up the incline before momentarily stopping. End of Question

FRQ — Circular Motion and Roadway Forces A small vehicle of mass 720 kg travels over the crest of a circular hill of radius 38.0 m. At the top of the hill, the vehicle moves at 14.0 m/s. The driver then enters a flat curve of radius 52.0 m. The coefficient of static friction between the tires and road is 0.680. (a) Draw a free-body diagram for the vehicle at the top of the hill and determine the normal force from the road on the vehicle. (b) Determine the maximum speed at the top of the hill before the vehicle would lose contact with the road. (c) Draw a free-body diagram for the vehicle on the flat curve and determine the maximum speed at which it can travel without skidding. (d) Suppose the road on the curve is banked at 12.0°. Determine whether the vehicle can travel through the curve at 18.0 m/s without relying on friction. Justify your conclusion. (e) Explain how the roles of the normal force differ in the hill-crest situation and the flat-curve situation. End of Question
