A ceiling fan is rotating counterclockwise with a constant angular acceleration of $0\mathrm{.}50ra\frac{d}{s^2}$ about a fixed axis

perpendicular to its plane and through its center. Assume the fan starts from rest.

$($a$)$ What is the angular velocity of the fan after $3\mathrm{.}4s?($Enter the magnitude.$)$

Your response differs from the correct answer by more than $10\%.$ Double check your calculations. rad$/$s

$($b$)$ What is the angular displacement of the fan after $3\mathrm{.}4s?($Enter the magnitude.$)$

$2$

Your response differs from the correct answer by more than $10\%.$ Double check your calculations. rad

$($c$)$ How many revolutions has the fan gone through in $3\mathrm{.}4s?$
