- Title
Maximizing the height or flight time for a vertical launch of fixed energy.
- Authors
Lipscombe, Trevor C.; Mungan, Carl E.
- Abstract
A standard problem in introductory physics is to determine the peak height and flight time of a ball projected at a specified initial speed without drag. Here a ball is instead launched vertically upward in the presence of quadratic air resistance with a fixed initial kinetic energy so that its launch speed depends on the mass of the ball, as does the quadratic drag force. The optimal radius of ball to reach either the greatest peak height or flight time is calculated.
