You are looking over a merry go round, and you notice that at t=0 it is rotating at 40 radians/sec. You decide to take two more readings, at t=1 sec (-10 rad/sec) and at t= 10 sec (-460 rad/sec). Is the merry go round undergoing angular acceleration? A) yes. the angular acceleration is counterclockwise. B) yes. the angular acceleration is clockwise. C) no. there is no angular acceleration D) alright I give up.
