1. A car wheel slows down from 70 rad/s to 42 rad/s in a time of 4.2 seconds. Determine (a) the angular acceleration of the wheel and (b) the number of revolutions the wheel makes in that time. 2. Of the following arrangement of masses, both moving about the same axis at an angular speed of 25 rad/s, if the separation distance between them is 10 cm, determine (a) the rotational inertia of the arrangement of masses and (b) the rotational kinetic energy. 4.00 kg 3.00 kg 3.
