The wheel of a car has a radius of 0.320 m. The engine of the car applies a torque of 288 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?
A mechanic pushes a 2.20 x10^3 kg car from rest to a speed of v, doing 5400 J of work in the process. During this time, the car moves 28.0 m. Neglecting friction between car and road, find each of the following.
Question: Field and force with three charges? What is the electric field at the location of Q1, due to Q 2 ?
