In the process of starting up the car plant, a turbine accelerates from rest at 0.49 rad/s^2 .How long does it take to reach its 4400 rpm operating speed?

How many revolutions does it make during this time?

I got 940 s for the first part, but for the second part Do i use the formula theta=w^2/2(.49/2pi)

I am very lost on the second part.

I am very lost please help. I determined that
