A 60kg student is running with a speed of 6.3m/s when she leaps onto a disc-
shaped play ground toy at the position shown. The 115kg disc is free to around it's
fixed center and has a radius of 1.4m.
The moment of inertia of a point (like the student) is I = mr?. The moment of inertia
of any disc is I = /2mr?.
