What is the angular velocity of the merry-go-round now

Reference no: EM131926414

A 5.0 m diameter merry-go-round is rotating freely with an angular velocity of 0.50 rad/s. Its total moment of inertia is 2500 kg·M². Four people standing on the ground, each of 65 kg mass, suddenly step onto the edge of the merry-go-round.

(a) What is the angular velocity of the merry-go-round now?

ω =

rad/s

(b) Assume that the people were on it initially (when the angular velocity is 0.50 rad/s) and then jumped off in a radial direction (relative to the merry-go-round). What would be the angular velocity of the merry-go-round?

ω =

rad/s

For A I got 0.3 and for B I got 0.825

A was correct B was incorrect.
