Question

A playground merry-go-round of radius $R=2.00 \mathrm{m}$ has a moment of inertia $I=250 \mathrm{kg} \cdot \mathrm{m}^{2}$ and is rotating at 10.0 rev/min about a frictionless, vertical axle. Facing the axle, a 25.0 -kg child hops onto the merry-go-round and manages to sit down on the edge. What is the new angular speed of the merry-go-round?

Name: A playground merry-go-round of radius R=2.00 m has a moment of inertia I=250 kg·m^2 and is rotating at 10.0 rev/min about a frictionless, vertical axle. Facing the axle, a 25.0 -kg child hops onto the merry-go-round and manages to sit down on the edge. What is the new angular speed of the merry-go-round?

Step 1

0 \text{ rev/min}$ and initial moment of inertia, $I = 250 \text{ kg} \cdot \text{m}^2$. The initial angular momentum, $L_{\text{initial}} = I \omega$. Show more…
