SUMMARY
The average angular acceleration of a spinning wheel transitioning from 43 RPM to 62 RPM over 15 seconds is calculated using the formula α = Δω / t. The change in angular velocity (Δω) is determined by converting the RPM values to radians per second, resulting in a Δω of approximately 1.3 * 10^-1 rad/s². Additionally, the angular momentum (L) must be calculated as a vector, and the change in angular momentum should be derived through vector subtraction before equating it to I * α.
