Subtract her kinetic energy at the bottom of the slide from her potential energy at the top.
M g H - (M/2) V^2 = 1102.5 - 112.5 = _____ J
The difference is the work lost to friction. (Work done BY friction is considered negative, so they may want you to put a minus sign before the answer)
need help quick:
Magen's mass is 25 kg. She climbs the 4.5-m ladder of a slide, and reaches a velocity of 3.0 m/s at the bottom of the slide. How much work was done by friction on Magen?
