10.2 Exercise 10

A wheel 1.0 m in radius rotates with an angular acceleration of $4.0 \text{rad} / \text{s}^{2}$. (a) If the wheel’s initial angular velocity is 2.0 rad/s, what is its angular velocity after 10 s? (b) Through what angle does it rotate in the 10-s interval? (c) What are the tangential speed and acceleration of a point on the rim of the wheel at the end of the 10-s interval?
