Achild sits on a merry‑go‑round that has a diameter of 5.00 m. the child uses her legs to push the merry‑go‑round, making it go from rest to an angular speed of 20.0 rpm in a time of 48.0 s. what is the average angular acceleration of the merry‑go‑round in units of radians per second squared (rad/s2)? = /s2 what is the angular displacement δtheta of the merry‑go‑round, in units of radians (rad), during the time the child pushes the merry‑go‑round? δtheta= what is the maximum tangential speed of the child if she rides on the edge of the platform? =/s
