Question

A playground merry-go-round with a mass of 115 kg and a radius of 2.1 m is rotating with an angular frequency of 0.42 rev/s.

Randomized Variablesm₁ = 115 kg
m₂ = 17 kg
ω_i = 0.42 rev/s
r = 2.1 m

What is the magnitude of its angular velocity, in radians per second, after a 17 kg child gets onto it by grabbing its outer edge? The child is initially at rest.
