Excerpt from The Force of Impact on a Sphere Striking a Water Surface This paper furnishes an explicit mathematical treatment of the impact forces on a projectile with a spherical nose entering water vertically. On the basis of the results obtained, a less technical memorandum will follow stressing the more intuitive physical aspects of the problem. In addition, an extension of the theory to the problem of oblique entry is being considered. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
