Assume the hillis a 10 degree incline. A. How far up the hill does the car travel before it starts to slide back down? Make sure toinclude the initial 10 meters in your final distance. B. If the car then slides all the way back to the bottom of the hill, what is its speed when itgets to the bottom? Assume it doesn’t gain traction back, so it is sliding with no frictionthe whole way down.
