Rotation, Moment of Inertia In this lab, we will look at two blocks attached to the ends of a rope which is wrapped around a pulley. This arrangement is usually referred to as an "Atwood machine". As you can see, at some point in time the electric brakes inside the pulley support bracket are released and, subsequently, the pulley can rotate freely on an almost frictionless axle. The masses of the blocks are mR 11.00 kg (right) and m₁ = 10.00 kg (left). • Assume the rope is massless and does not stretch. • The diameter of the pulley wheel is 14.5 cm.

Assume the pulley has the shape of a uniform disk. Use your value of the acceleration to calculate the mass mp of the pulley. mp = kg
