Homework Help: PHYSICS

Posted by Kelsey on Thursday, October 27, 2011 at 2:52pm.

An object is originally moving at 13 m/s at the top of a frictionless, quarter-circular ramp with a radius of R = 13 meters. It then travels on a frictionless horizontal surface, around a frictionless loop of radius r = 2 meters, across another horizontal, frictionless surface. The then encounters a frictionless incline of length 13 meters angled at 21 degrees. At the top of this incline is a horizontal surface with a coefficient of kinetic friction of 0.2. The object then stops on this horizontal surface due to friction. How far does the object travel on the horizontal surface in meters?

help please .
