Hey, I have a question about how to calculate the air resistance, and eventually how much more energy is required to get the same result, once air resistance has been factored in.
I have thought of two ways to solve the problem: One way requires multi-variable calculus, which I havn't had, the other way entails breaking the equation into x & y components.
The problem I have is as fallows. I have a tennis ball, which has a mass of 57g, that is fired at velocity V and at angle A. If air resistance can be ignored, it will land right on target, however, air resistance can not be ignored. I need to find how much I need to increase the initial velocity, in order to achieve the same result, or alternatively how much I need to change the launch angle.
It seems like this would be a common ballistics question, but I have been unable to find an equation. Any help is greatly appreciated! Thanks in advance, - Peter
P.S. Here is a good calculator that is related to my problem http://galileo.phys.virginia.edu/classes/109N/more_stuff/Applets/ProjectileMotion/jarapplet.html
