10.8 Exercise 26

Avg difficulty 2.5

The angular acceleration of a rotating rigid body is given by α=(2.0−3.0t)rad/s2\alpha = \left(2.0 - 3.0 t\right) \text{rad} / \text{s}^{2}. If the body starts rotating from rest at t=0t = 0, (a) what is the angular velocity? (b) Angular position? (c) What angle does it rotate through in 10 s? (d) Where does the vector perpendicular to the axis of rotation indicating 0°0 ° at t=0t = 0 lie at t=10st = 10 \text{s}?
