A car of mass m = 1130 kg is traveling down a θ = 11 degree incline. When the car's speed is v0 = 11 m/s, a mechanical failure causes all four of its brakes to lock. The coefficient of kinetic friction between the tires and road is μk = 0.38.

Part (a) Write an expression for the magnitude of the force of kinetic friction, fk.

= μk m g cos theta

Part (b) Write an expression for the change in the car's height, h, along the y-direction, assuming it travels a distance L down the incline.

h= -L sin theta

Part (c) Calculate the distance the car travels down the hill L in meters until it comes to a stop at the end.

L=
