a 1750kg car is parked at the top of a hill with an incline of 12 degrees. Its brakes fail and the car starts rolling down the hill. a) how long will it take for the car to travel 200m and reach the bottom of the hill? (the coefficient of rolling friction between the tires and the road is 0.10) b) what will be its velocity at the bottom?
