  1. Sep 23, 2006 #1
    A child slides down a slide with a 28 degrees incline and at the bottom her speed is preisely half what it would have been if the slide had been firctionless. Caluclate the coefficient of kinetic friction bewteen the slide and the child.

    So what have you done?

    Hint: Solve for the frictionless case, and for the kinematics consider uniform acceleration.
