Document Summary

Often the projectile that we are launching is out own body. When measuring the maximum height that can be achieved with a vertical jump, the measure issued to finger height. We can rearrange our body segments about our center of mass to get a little more finger tip height. A special case is pole vault, where the bending of the pole converts horizontal speed into vertical speed. The distance travelled horizontally is found as follows: The sweet spot is 45 degrees, compromise of having enough hang time and enough horizontal distance. Always a pair, one will send you higher one will send you longer. Chip and roll or wedge in golf - both parabolas. For the same takeoff component, started from higher give a greater horizontal distance. For the same takeoff height, a faster horizontal component will give a larger horizontal distance. With too high a takeoff angle, with the same takeoff velocity, you can shorten the distance travelled.
