Determine the angular velocity of the merry-go-round if A jumps off horizontally in the n direction with a speed v , measured with respect to the merry-go-round.What is the merry-go-rounds angular velocity if B then jumps off horizontally in the + t direction with a speed v , measured with respect to the merry-go-round? Neglect friction and the size of each child. 659...
