A child 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 19.0 rpm in a time of 50.0 s.
-What is the average angular acceleration avg of the merry‑go‑round in units of radians per second squared (rad/s2)?
-What is the angular displacement Δ of the merry‑go‑round, in units of radians (rad), during the time the child pushes the merry‑go‑round?
-What is the maximum tangential speed max of the child if she rides on the edge of the platform?
