I'm having some trouble with this question. Not sure how to go about solving it. Any help would be appreciated. Thanks.
An object is made up of a disk (M=7.0kg, R=2.0m) and two point masses (m1=3.0kg and m2=4.0kg). The arrangement of the disk and the point masses are shown in the figure and the dimensions are d1=1.0m, d2=1.5m, d3=0.5m, d4=1.0m, and t=0.3m.
A. What is the x-coordinate of the center of mass of the object?
B. What is the z-coordinate of the center of mass of the object?
C. What is the moment of inertia of the object about rotation axis z?
D. What is the moment of inertia of the object about rotation
axis I (the moment of inertia of a disk rotating about its
edge is 
?

Problem 3: A merry-go-round can be considered a uniform disk of mass 145 kg and radius 2.10 m free to rotate about a frictionless axis through its center. A 40.0 kg child stands at the edge and the system is initially rotating at 0.300 rad/sec. The child begins to walk around the edge of the merry-go-round with a velocity of 0.250 m/s relative to the ground in the direction of the rotation. What is the angular velocity of the merry-go-round...

Page 13 9. A 49.8-kg athlete running at 4.54 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.45 m from the axis of rotation of the merry-go-round. She is traveling tangential to the edge of the merry-go-round just before jumping on. The moment of inertia about its axis of rotation is 625 kg m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after she has jumped onto it?...
