SUMMARY
The discussion focuses on calculating the angular displacement of a variable speed electric drill motor that accelerates from 100 rev/s to 210 rev/s at a rate of 53.0 rev/s². The correct approach involves using the rotational analogue of the kinematic equation Vf² = Vi² + 2ax, where Vf is the final angular velocity, Vi is the initial angular velocity, and a is the angular acceleration. The calculation yields an angular displacement of 15,700 revolutions, which was initially miscalculated. The correct methodology confirms the importance of applying the appropriate rotational equations for accurate results.
