Part A what was it's average angular acceleration?Part B for what length of time did the wheel rotate? Express the answer using 3 significant numbers After fixing a flat tire on a bicycle you give the wheel a spin. Its initial angular speed was 5.50 rad/s and itrotated 14.5 revolutions before coming to rest. You may want to review (Pages 305-307).

Question

Part A what was it's average angular acceleration?

Part B for what length of time did the wheel rotate?

Express the answer using 3 significant numbers

After fixing a flat tire on a bicycle you give the wheel a spin. Its initial angular speed was 5.50 rad/s and it
rotated 14.5 revolutions before coming to rest. You may want to review (Pages 305-307).

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
