question
A driver applies brakes and slows down the car at a constant rate of 25 fps^2 till it comes to rest. The car weighs 3500 lbs. and its average speed is 55 mph. If the drum diameter is 10 in., band face width and thickness are 2 in. and (1 / 4) in. respectively, determine the following: (a) the temperature increase in the drum due to heat absorption, (b) mean rate at which the drum absorbs power in the first second, (c) average power absorbed on the whole.
