Homework Statement
A rolling wheel moving to the right initially has an angular speed of 7.0 rad/s but after making 3
complete revolutions the wheel has a final angular speed of 11.0 rad/s. What is the magnitude and direction of the average angular acceleration of the wheel?
Homework Equations
(w2-w1)/(t2-t1) or maybe I need to use that equation and some rotational kinematics equations, not positive.
The Attempt at a Solution
I tried saying my time was 3 seconds but I am having trouble identifying the time. Not really sure where to start with this problem.
