Question: 4. A man pushes a merry-go-round (a disk rotating about its central axis, with mass M : 200.0 kg and radius R : 2.5 m)

4. A man pushes a merry-go-round (a disk rotating about its central axis, with mass M : 200.0 kg and radius R : 2.5 m) with a constant force of 75.0 N on the outer edge. Determine the torque provided by the man. How long does it take to accelerate the merry-goround from rest to a speed of 4.0 rad/s? When this speed is achieved his two kids (m1 = 30.0 kg, m2 = 25.0 kg) jump on the ride and each land a distance of .50 m from the outer edge. Approximating the children as point masses determine the angular velocity of the merry-goround after they jump on. \\w
