A student is riding on the edge of a spinning merry-go-round (MGR); he is sitting cross-legged on the MGR edge, facing radially outwards, and holding a sandbag so that if he releases the sandbag it will fall onto the ground just beyond the MGR edge. Suddenly, he releases the sandbag; it falls to the ground where it sticks and thus stops moving. Consider the following statements concerning angular momentum, as measured about the central vertical axle of the merry-go-round, in this experiment. Select all true statements.
| The angular momentum of the system consisting of the sandbag, together with the merry-go-round and the student, is constant. |
| The angular momentum of the merry-go-round is constant. |
| The angular momentum of the student is constant.. |
| The angular momentum of the sandbag is constant. |
| The angular momentum of the system consisting of the student and the merry-go-round is constant. |

A child sits at the outer edge of a merry-go-round (MGR) at a neighborhood park. The MGR has a radius of R = 1.5m and a rotational inertia of IMGR = 140kgm2. The child has a mass of 40kg and contributes some to the rotational inertia of the spinning system: I = IMGR + IChild. The MGR is spinning with an angular speed of 2.0s−1 when the child begins dragging her foot on the ground to bring the MGR to...

1. Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.80 m. The merry‑go‑round is spinning at 22.0 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...
