Suggested Answer
Jill's linear velocity is half of Bonnie's.jill and bonnie moves in a circular path with the same speed as in the speed of the merry go round.The linear velocity of the body can be calculated as V= ω*Rhere the V = tangential velocity/linear velocity (m/s)ω = angular speed (rad/sec)R = radius where body is located from the center of circular path.we know, 1 rev=2π radω = 1 rev/2sec = 2π rad/2s = π rad/sbonnie linear velocity (vB)vB = ω*R = π*R(m/s)jills linear velocity (vJ)vJ = ω*R/2 = (1/2) (π*R) (m/s) Therefore, Jill's linear velocity is half of Bonnie's.To know more about tangential velocity https://brainly.com/question/28738284#SPJ4
