A child, whose weight is 334 N,runs at 2.76 m/s tangent to the rim of the merry-go-round and jumpsonto it in the direction opposite of its sense of rotation. Withwhat angular speed does the merry-go-round rotate after the childjumps onto its edge?

I'm pretty sure the answer is going to be negative.
