A solid body starts rotating about a stationary axis with an angular acceleration a = (2 x 10 ^ -2)t rad/second squared., here t is in seconds. How soon after the beginning of rotation will the total acceleration vector of an arbitrary point of the body form an angle theta = 60 degrees with its velocity vector?
