1a. 1b. A disk with a rotational inertia of 1.20 kg·m2 rotates like a merry-go-round while undergoing a torque given by τ = (4.01 + 2.79t) N · m. At time t = 1.00 s, its angular momentum is 3.53 kg·m2/s. What is its angular momentum at t = 3.00 s? In the figure here, three particles of mass m = 0.013 kg are fastened to three rods of length d = 0.13 m and negligible mass. The rigid assembly...
