A fan blade starts at rest and begins moving with a constant angular acceleration of 2.00 rad/s2. The blade rotates through an angle of 285 radians in an 11.0 s interval that did not start at t = 0s. How long did it take the blade to reach the beginning of the 11.0-s interval? Answer must be in seconds.
A fan blade, initially at rest, rotates with a constant acceleration of 0.025 rad/s2. Whatis its angular speed at the instant it goes through an angular displacement of 4.2 revs?1.1 rad/s is the correct answer.
