Consider a rotational frame like the one sketched above. The moment of intertia (or the "rotational mass") of the frame is

I = 0.0080 kg m2

A string is wound around the central shaft. The radius of this shaft is 0.75 cm (or 0.0075 m). The string goes over a pulley and is attached to a hanging mass of 0.150 kg.

What is the acceleration of the hanging mass?

1.00 m/s 2.

0.10 m/s 2.

0.01 m/s 2.

10.0 m/s 2.
