A shaft is turning at (65.0 rad./s) at time zero. Thereafter, its angular acceleration is given by:where (t)is the elapsed time.
(a) Find its angular speed at (t=3.0 s).
(b) How far does it turn in these (3 s)?
(c) Find the time until the shaft stops.
(d) Calculate the number of turns until the shaft stops.
