    Solving Physics Puzzle: Prove Guy Slides off Ice Mount at 2/3R Height

    Fn-mgcosx=-mv^2/R gravitational potential is zero at the top then potential energy at the time shown is u = -mgR(1-cosx) he starts at rest conservation of energy gives 0 = .5mv^2-mgR(1-cosx) substitute above equation into one for second law to obtain gcosx = 2g(1-cosx) cosx = 2/3 h =...
