Walker, Halliday & Resnick β Rolling, Torque, and Angular Momentum: Problem 42
42 Figure 11-40 gives the torque $\tau$ that acts on an initially stationary disk that can rotate about its center like a merry-go-round. The scale on the $\tau$ axis is set by $\tau_s = 4.0 \text{ N}\cdot\text{m}$. What is the angular momentum of the disk about the rotation axis at times (a) $t = 7.0 \text{ s}$ and (b) $t = 20 \text{ s}$?
π Solution Approach
Find: (a) $t = 7; (b) $t = 20 \text{ s}$?
