I need help with part a,b,c,d. Thank you for your help

A 60-kg student stands on a merry-go-round at a distance of 1.2 m from the center as shown
below. The merry-go-round may be considered to be a uniform solid disk with a mass of 15-bs
and a radius of 5.0 meters. The system is initially rotating at 30 RPM in a counterclockwise
direction when the student begins to walk toward the rim of the mery-go-round. If the student
may be considered as a point mass, determine;
> > > >
A The student's initial moment of inertia in kg-m².
b. The student's initial angular momentum in kg-m²/sec.
c.
The initial angular momentum of the merry-go-round in kg-m²/sec.
d. The final angular velocity of the system when the student reaches the rim in rads's.
