A wheel starting from rest is uniformly accelerated at 4rad\sec^2 for 10s.It is allowed 2 rotate uniformly for 10s and finaly brought 2 rest in 10s.Find total angle rotated by wheel.Plz tell me whats the ans and how?

W = (alfa)t

total angle rotated = Wt + (alfa)t2

                           =  2(alfa)t2                                (alfa is angular accleration)

                           =2(4)100=800rad
