You are sitting on a merry-go-round of mass 200 kg and radius 2m that is at rest (not spinning). Your mass is 50 kg. Your friend pushes the edge of the merry go round with 100 N of force, applied at a 90 deg angle. (hint: the merry-go-round is a disk).
a. How much torque did your friend apply?
b. What is your angular acceleration if you are sitting in the middle of the merry-go-round?
c. What is your angular acceleration if you are sitting at the edge of the merry-go-round?
d. Which angular acceleration is larger and why?

Two students are on opposite sides of a merry-go-round of radius 2.1 m and mass 64 kg. One pushes tangent to the outer edge in the clockwise direction with a force, F. The other pushes in the counter-clockwise direction with a force of 33 N. Model the merry-go-round as a disc (I=1/2MR2). If the angular acceleration of the merry-go-round is 0.32 rad/s2, what is the magnitude of force F?
