work done by friction=? as big M slides through a distance of 3 meters.
what is the speed of small m when it hits the ground?
M=5kg m=2kg m is 3meters above ground muk is.25
I can't figure out how to post a drawing (first post)Big M is horizonatal and frictionless b4 muk attached by a string over a pulleyattached by same string to m which is the 3 meters above ground.
wf = -fkd wf=e2-e1
