Question
A 6.0-kg block slides from point A down a frictionless curve to point B. After the block passes point B, a friction force opposes the motion of the block so that it comes to a stop 2 m from B. Calculate the coefficient of kinetic friction between the block and the surface after position B
Explanation / Answer
conserving the energy
mgh=umgx where u =coeff of frition
ux=h
u=1/2
u=0.5
