A car of mass m = 1100 kg is traveling down a θ = 11 degree incline. When the car's speed is v0 = 15 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 = 0.45. 1.Write an expression for the magnitude of the force of kinetic friction, fk.  2.Write an expression for the magnitude of the change in the car's height, h, along the y-direction, assuming it travels a distance L down the incline.  3.Calculate the distance the car travels down the hill L in meters until it comes to a stop at the end.
