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? sig.gif?tid=8O75-46-CB-41-82C6-22885 (I believe the answer is 301.15)

b. What is the angular acceleration of the grindstone α0, in radians per square second, assuming negligible friction?

c. What is the angular acceleration of the grindstone αf, in radians per square second, if there is an opposing frictional force of 19 N exerted 0.35 m from the axis?

    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...
