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
200
alpha
What is angular acceleration
200
angular acceleration
rad/ s2
200
from rpm to rad/s
multiply by 2Pi and divide by 60

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

theta
What is angular displacement
300
angular velocity
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)

A circular saw blade 0.2 m in diameter starts from rest. In 6s, it accelerate with constant acceleration to an angular velocity of 140 rad/s.
What is the angle through which the blade has turn?
