A solid plastic sphere as shown in the figure (mass m=1 kg, and radius r = 10 cm ) initially at rest starts to rotate about its axis owing to a tangential force F as shown. The ball reaches the velocity v=10 m/s in 5 sec after the start. (a) Find the magnitude of the force F in Newtons. (b) If the force is applied as shown below, will the ball still need the same magnitude of F or not to reach that velocity in 5 sec, Yes or No? Explain.

Three children are riding on the edge of a merry-go-round that has a mass of 105 kg and a radius of 1.50 m. The merry-go-round is spinning at 18.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry-go-round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry-go-round can be treated as a solid disk and the children as point masses.
