Homework Help: Roller Coaster Dynamics

  1. May 2, 2012 #1
    The attached problem has clearly confused me. I tried solving it, but I get to a point where I cant go any further. If someone could point me in the right direction I appreciate it. Also the calculations topwards the bottom of the page are from me attempting to solve.

    Thanks in advance

    Use SI units
    Calculate KE at start
    Calculate Ke at bottom
    Use centripetal acceleration for the curved part
