You are driving a 1000 kg car in a race against a monster truck (10000 kg) and a clown car (300 kg). You are all moving with the same velocity (20 m/s) when all the driver suddenly slams on the brakes, locking the wheels. (All three cars have identical tires somehow so the coefficient of kinetic friction between the road and tires is 0.2). (a) Which car travels the longest distance to skid to a stop? (b) For which car does friction do the largest amount of work in stopping the car?
