Question

A cube of mass ?? is initially at rest at the
peak of an inclined plane, which has a height
of 4.6 m and has an angle of θ = 25° with
respect to the horizontal. After it has been
released, you notice it to be traveling
at v = 5.5 m/s as it leaves the ramp. What is
the coefficient of kinetic friction along the
ramp?
