Q1. The wheel of the car has a radius of 0.340 m. The engine of the car applies a torque of 282 N•m to this wheel, that does not slip against the road surface. Since the wheel does not slip, the road must be applying the force of static friction to the wheel that produces a counter torque. Moreover, the car has a constant velocity, so this counter torque balances the applied torque. What is the magnitude of the static frictional force?

Q2. A wheel of diameter 25.00 starts from rest and rotates with a constant angular acceleration of 5.00. At the instant the wheel has computed its second revolution; calculate the radial acceleration of a point on the rim in two ways.
