Kinematic Problem

  1. Aug 31, 2008 #1
    Please see the attached problem I came up with. I've done similar problems to this in school, but never with the frictional force acting along a curve. I'm wondering if my solution is valid, or if the integral needs some work?

    And I just realized I left out the mass [M] in the normal force equation, and all other equations that use it.
