bonnie sits on the outer rim of a merry-go-round, and jill sits midway between the center and the rim. the merry-go-round makes one complete revolution every 2 seconds. what is jill's linear velocity compared to bonnie's? explain
what is the power output p, of the shot-putter, in terms of g (the acceleration due to gravity) and the variables given in the problem statement. (do not include the power required to accelerate his body.)
