If the coefficient of kinetic friction is 0.2, what friction ofthe total mechanical energy is lost due to frictional forces?
Run#
Mass of hanger + weights (M)
mass of glider +flag (m)
velocity of glider (v)
d (m)Ă‚Â Ă‚Â
potential energy lost (Mgd) (J)
Kinetic energy gained 1/2 (m+M)v2
% change (ME)
