## Homework Statement

An object of mass 13 kg is placed on incline with friction. Incline is originally horizontal and then raised slowly and at 22 degrees, mass begins to slide down incline. It is found that coefficient of kinetic friction is .83 times coefficient of static friction. If incline is raised to 41.3 degrees and object enters bottom of ramp at some velocity and its velocity at top of incline is 24 m/s, what would be its velocity at bottom of incline in m/s if height (not length) of ramp is 10.5 meters? Answer is 29.61.
