Answer:
<em>Angular displacement=68.25 rad</em>
Explanation:
<u>Circular Motion</u>
If the angular speed varies from ωo to ωf in a time t, then the angular acceleration is given by:
The angular displacement is given by:
The wheel decelerates from ωo=13.5 rad/s to ωf=6 rad/s in t=7 s, thus:
Thus, the angular displacement is:
Angular displacement=68.25 rad
