A particle starts from rest and moves on a curve with constant angular acceleration of `3.0 rad//s^(2)`. An observer starts his stopwatch at a certain instant and recond that the particle covers an angular span of `120` rad at the end of `4^(th)` second. How long the particle has moved when the observer started his stopwatch?
