Asked by Jermaine

A mass of 1.0 kg is located at the end of a very light and rigid rod 44 cm in length. The rod is rotating about an axis at its opposite end with a rotational velocity of 3 rad/s.
(a) What is the rotational inertia of the system?

kg · m2

(b) What is the angular momentum of the system?

kg · m2/s
