Homework Help: Speed at the bottom of the track

  1. Apr 20, 2012 #1
    1. The problem statement, all variables and given/known data
    A child slides down a curved playground slide that is one quadrant of a circle of radius R. If he starts from rest and there is no friction, find his speed at the bottom of the track. (the motion of this child is exactly the same as that of a child on a swing of length R, with the other end held at point 0)


    2. Relevant equations
    I can't figure this one out, really could use some help. Anyone know how to get me started at least?


    3. The attempt at a solution
