Consider what happens when an object decelerates.
Question 5.
A rotating disk has an angular velocity of 8 rad/s and maintains this speed for 5 seconds before slowing down to 2 rad/s. Determine the angular acceleration over the time period.
Show hintHide hint
Focus on the change in angular velocity over time.
Question 6.
