gravity force down the plane=mg*sinTheta
friction force up the plane=mu*mg*cosTheta
net force=mass*a
mg(sinTheta-mu*CosTheta)=m*3.3
solve for mu
A block accelerates at 3.3 m/s2 down a plane
inclined at an angle 27.0�.
m

27�
Find μk between the block and the in-
clined plane. The acceleration of gravity is
9.81 m/s2 .
