Jan 19	comment	Calculating projectile range from known maximum height and time traveled I think I understand now. Thanks. Now to figure out another way to estimate horizontal velocity.

Jan 19	comment	Calculating projectile range from known maximum height and time traveled Wouldn't the time in the air also be a function of horizontal velocity? As the angle changes, you can reach the same height but have wildly varying hang times and ranges as a result. As the projectile is stationary at launch and would have a predictable trajectory, I'm struggling to understand how they are only functions of $v_y$.

Jan 18	comment	Calculating projectile range from known maximum height and time traveled Thanks, I'm planing on using real world sensors for this, so I'll eventually have to factor in wind resistance, but for now perfect conditions will do. I'm using $9.8m/s^2 * dt/2$ to calculate $v_0x$ which calculates the time between the launch and the time that the vertical velocity = 0 (half the flight time for now). I'm still assuming that I'll need the angle of launch to appropriate the range however.
