Assignment:
A ceiling fan has one red blade. Initially rotating in a counterclockwise (positive direction) with angular velocity Wo= +30 radians per second.
At that instant, when the red blade makes an angle Qo= +1.4 radians from the +x axis, the current is reversed and a timer is started at 0 seconds. From that instant, the rotating fan continues through additional 60 radians while coming to a momentary stop and reversing direction, all at a constant angular acceleration.
a. Find A, the angular acceleration.
b. Develop an equation giving Q(t), the angular position as a function of time.
c. Find the angle in radians, between the plus x axis and the red blade at the
instant of the momentary stop.
d. Show a graph of Q(t) from part b.
