3. Rolling motion of a hoop
Using conservation of energy, prove that a hoop released from a vertical height h above the bottom of the
incline reaches the bottom with a speed of √gh. Hint: It has both translational and rotational kinetic energy
as it rolls down the ramp.
Incline the wooden track with one block placed vertically underneath the end of the track, opposite side from
the hinge and determine the ramp's incline angle 0.

The hoop's mass is 300 g. Measure the radius of the hoop R and calculate the hoop's moment of inertia I and
acceleration acM as it rolls down the incline.
