A metal hoop lies on a horizontal table, free to rotate about a fixed vertical axis through its center while a constant tangential force applied to its edge exerts a torque of magnitude 1.00 ✕ 10−2 N · m for 1.40 s. (a) Calculate the magnitude of the hoop's change in angular momentum (in kg · m2/s). ? kg · m2/s (b) Find the change in the hoop's angular speed (in rad/s) if its mass and radius are 0.270 kg and 0.180 m
