Re: Physics: ball launch using gravity

I posted an Excel spreadsheet that computes the ball trajectory for Aim High. You can adjust the launch angle, velocity, and see the effect of air resistance (which should be really small) for your problem. To "turn off" air resistance, you can set the drag coefficient (Cd) to zero. The spreadsheet can be downloaded from this post:
