A merry-go round of radius R = 2 m has a moment of inertia I =250kg m2, and is rotating at w0 = 1 rad/sec.A child whose massis m = 25 kg hops onto the edge of themerry-go-round.
- Find the angular momentum and kinetic energy ofthemerry-go-round before the child had hopped on it
- Find the angular velocity, angular momentum and kineticenergyof the system after the child lands on themerry-go-round
- If the child starts walking on the rim at a velocity of 1m/secin the direction of rotation, what will be the angularvelocity ofthe merry-go-round?
