1. Sarah sees a playground merry-go-round platform that has a radius of 3.50m at the bottom of the hill. She gets it rotating up to an angular velocity of 2.5rad/s. The merry-go-round has a moment of inertia = 650kg-m². Assume the motion is constant with no friction. a. What is the angular momentum of the merry-go-round?

b. Sarah's 60kg friend Maggie jumps onto the merry-go-round and she lands at a distance of
2.75m from the center of the merry-go-round. What is the new angular velocity of the
merry-go-round? Also, state what principle you used to solve the problem.
