A 135kg merry-go-round is initially at rest, when a student holding the rail begins
to run, generating the normal force shown for 1.7s. The equation for the
moment of inertia of any disk (such as a merry-go-round, neglecting the hand
rails) is I = 1/2mr.
Answer all questions relative to the center of the merry-go-round.

377 Nm
What is the moment of inertia?
114
kg m^2
What is the angular acceleration?
unit
What is the final angular speed?
rad/s
rpm
