    Figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.00 m and a mass of 20 kg and is initially at rest. Starting at time t = 0, two forces are to be applied tangentially to the rim as indicated, so that at time t=1.25 s the disk has an angular velocity of 250 rad/s counterclockwise. Force F1 has a magnitude of 0.100 N. What is magnitude F2? TE

    Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.00 kg m about its central axis, is set spinning counterclockwise at 550 rev/min. The second disk, with rotational inertia 6.40 kg m about its central axis, is set spinning counterclockwise at 800 rev/min. They then couple together. (a) What is their angular speed after coupling?...
