Repeat Problem 43, but now assume the person is holding a 5.0-kg mass in each hand.

Data from Problem 43

Consider a person who is sitting on a friction less rotating stool as in Figure P9.43. The person initially has his arms outstretched and is rotating with an angular speed of 5.0 rad/s. He then pulls his arms close to his body.

Concerned with the magnitude of the angular momentum, not its sign.
