A park merry-go-round consists of a 220 kg circular wooden platform 3.90 m in diameter. Four children runningalongside push tangentially along the platform's circumferenceuntil, starting from rest, the merry-go-round reaches a steadyspeed of one complete revolution every 2.8 s.

(a) If each child exerts a force of 26 N, how far does eachchild run (m)?

(b) What is the angular acceleration of the merry-go-round(rad/s^2)?

(d) What is the kinetic energy of the merry-go-round (J)?
