Q. The wheel of a car has a radius of 0.365 m. The engine of the car applies a torque of 284 N · m to this wheel, which does not slip against the road surface. Since the wheel does not slip, the road must be applying a force of static friction to the wheel that produces a countertorque. Moreover, the car has a constant velocity, so this countertorque balances the applied torque. What is the magnitude of the static frictional force?

Q. A 65 kg woman stands on the back of a 6.0 m long, 135 kg raft that is floating at rest in still water with no friction. The raft is 0.50 m from a fixed pier. The woman walks to the front of the raft and stops. How far is the raft from the pier now?
