Billy and his sled have a mass of 39.1 kg. He is at rest at the top of a 9.54 m long hill that has an angle of 35.01° from the horizontal. The hill has iced over and Billy is going to accelerate down the hill without any energy loss due to friction. Then move across the horizontal section of the land at the base of the hill. There is friction on the horizontal section and it will slow and eventually stop his motion.

You are to determine the horizontal distance he will travel along the horizontal section of the land.

The gravitational field strength on the planet with this hill is 11.10 m/s/s and the coefficient of friction on the horizontal section is 0.40.

The curvature at the bottom of the hill can be neglected.
