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 T = 15 N*m acting at the axle of the merry-go-round, and the merry-go-round is initially at rest. (Hint: Watch the following videos: "Session 9/Lecture/Rotational Motion Example Problems/Net Torque Example Problem 3") F = 90 N at 2 m O m = 25 kg at 1.5 m If = 10N at 1 m
