A parent exerts a torque on a merry-go-round at a park. The torque has a magnitude given by τ = 2.5θ2 + 11.0θ − 13.5, where the torque has units of newton meters when θ is in units of radians. (a) How much work is performed by the torque as the merry-go-round rotates through 1.50 revolutions, beginning at θi = 0? (answer in joules) (b) If it takes the merry-go-round 8.40 s to go through the 1.50 revolutions, what is the power transferred by the parent to the ride? (Enter the average power over 8.40 s.) (answer in Watts)
