Homework Help: Ap advanced physics

  1. Nov 10, 2004 #1
    A small block of mass (m) slides down a frictionless loop-the-loop track. The radius at the bottom of the track is R. The question is at what height above the bottom of the loop should the block be released so that it is on the verge of losing contact with the track at the top of the loop?

    (Currently studying potential and kinetic energy)

    Thanks for the help.
