Find the work involved in increasing her angular speed

Reference no: EM13334052

A ballerina spins initially at 1.06 revs/second when her arms are extended. She then draws in her arms to the body and her moment of inertia becomes 0.986 kg.m^2 while her spinning rate increases to 3.18 revs/second.

A) determine her initial moment of inertia and

B) the work involved in increasing her angular speed.
