6. A car is moving along a straight road at 60 mph [26.7 meter/sec ]. The driver makes slams on his breaks locking them so that the car skid s to a stop. Assume a constant braking force due to friction , and a kinetic friction coefficient of 0.70 between the tires and the road: (a) calculate the braking distance from the instant that the brakes were applied, (b0 how much work did the friction do in stopping the car?
