(35.1) An automobile, M= 1200 kg, is driving along a nat
=25m/s. [this corresponds to approximately 56 mph.] The driver brings the car to a stop by
applying the brake. We neglect the effects of drag (the car moves through air) and rolling
resistance.
(a) Compute the (i) initial, and (ii) final kinetic energy of the car.
(b) Suppose that the brake force is the net force acting on the car and compute the net
work done on the car.
(c) Mild Braking - Determine the car's stopping distance when $F_b = 500$ N.
(d) Moderate Braking - Determine the car's stopping distance when $F_b = 1500$ N.
(e) Strong Braking - Determine the car's stopping distance when $F_b = 2500$ N.
(f) Panic Braking - Determine the car's stopping distance when $F_b = 4000$ N.
