Homework Help: Physics

Posted by Tiffany on Monday, June 16, 2014 at 1:00am.

Josh starts his sled at the top of a 3.0m high hill that has a constant slope of 25 degrees. After reaching the bottom, he slides across a horizontal patch of snow. The hill is frictionless but the coefficient of kinetic friction between his sled and the snow is .05. How far from the base of the hill does he end up? Please note that the answer in the text book is 60m, and this is the chapter involving the application of Newton's laws. We have not reached energy yet so I don't think the solution has anything involving energy in it.
