An object initially rotating at an angular speed of 1.6 rad/sec turns through 30 revolutions during the time it experienced an angular acceleration of 0.32 rad/s^2
a) For how much time did the acceleration last?
b) What was the final angular speed?
Help please. Use the equation and then step by step and plug the numbers into that equation

I still need help. Use the kinematic equation to find the acceleration and final angular speed. Step by step to get the answer with the numbers into the kinematic equation. Please I don't understand
a. t = 1s/1.6rad * 6.28rad/rev * 30rev = 117.75 s.
b. V = Vo + a*t = 1.6 + 0.32*117.75 = 39.28 rad/s.
b. V = Vo + a*t = 1.6 + 0.32*117.75 = 39.28 rad/s.
