A grinding wheel is spinning at a rate of 20.0 revolutions per second. When the power to the grinder is turned off, the grinding wheel slows with constant angular acceleration and takes 80.0 s to come to a rest. How many rotations did the wheel make during the time it was coming to rest?

Really struggling with this concept.

Please explain so I can better understand !

Thank you so much

**Problem Description:** A grinding wheel is spinning at a rate of 20.0 revolutions per second. When the power to the grinder is turned off, the grinding wheel slows with constant angular acceleration and takes 80.0 seconds to come to a rest. **Question:** How many rotations did the wheel make during the time it was coming to rest? **Diagram/Graph Explanation:** There are no diagrams or graphs associated with this problem. The question focuses on calculating the total number of rotations using the given information on angular speed and time to rest.
