The angle through which a merry go round has turned varies with time according to theta(t) = 0.400[rad/s] t + 0.012[rad/s^3] t^3. What is the initial angular velocity?
0.400 rad/s

The rotating blade of a blender turns with a constant acceleration 1.50 rad/s^2.How much time does it take to reach an angular velocity of 36.0 rad/s starting from rest?
What is 24s

rad/ s
300
from rad/s to rpm
multiply by 60 and divide by 2Pi

This angular formula is useful when time t is not given
(omega final)^2 - (omega initial)^2= 2(alpha)*(theta final - omega initial)
