What must be the minimum coefficient of friction mu between the tyres of the drive wheels of a car and the road, if the car and the road, if the car of mass m=2 tons and load M=4 tons, has an acceleration a=0.2 ms^(-2) ? Consider the problem for two cases : (a) all the wheels are driven , (b) only the rear wheels are driven. Assume that the centre of gravity of the car lies at the mid-point between the axes of the wheel and the centre of gravity of the load above the rear axle.
