Suppose you exert a force of 190 N tangential to the outer edge of a 1.585-m radius 75.5-kg grindstone (which is a solid disk).
a. What is the torque τ, in newton meters, you are
exerting on the grindstone, relative to the center of mass of the
grindstone? (I believe the answer is
301.15)

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
