A disk with a rotational inertia of 7.00 kg m2 rotates

Chapter 11, Problem 40

(choose chapter or problem)

A disk with a rotational inertia of 7.00 kg m2 rotates like a merry-go-round while undergoing a variable torque given by T = (5.00 + 2.00t) N m. At time ( = 1.00 s, its angular momentum is 5.00 kg m2 /s. What is its angular momentum at t = 3.00 s?
