Question

A car accelerates from rest on a horizontal surface. The engine provides a torque of τ = 200 Nm on each of the two front wheels. Each of the four wheels on the car weigh m = 15 kg, have radius R = 35.0 cm and can be considered solid, uniform discs. The rest of the car (not the wheels) has a mass of M = 1000 kg. a) What is the acceleration of the car? I am trying to solve this with force and torque equation. The car now starts going up an incline of angle θ = 15◦. b) If the engine is turned off, what is now the acceleration of the car? c) What should the torque on each of the front wheels be, so that the car continues up the hill at constant speed?
