1. The problem statement, all variables and given/known data mass = 100 Kg Cross Area = 4 Drag = .4 Initial velocity = 17.59 m/s Gravity = 9.81 Angle Changes according to the position of the mouse Terminal velocity = 31.649 ; Don't know if its relevant but I calculated this 2. Relevant equations Y1 := X*tan(ang)-9.81*(X^2)/(2*((Vel*cos(ang))^2)) ; This is the equation without drag 3. The attempt at a solution I have looked up everywhere for Drag equations, but I can't find an equation That solves for the height Y at intervals of X That has all the variables I have anything not listed isn't relevant or shouldn't be Everything is constant If there is anybody able to help me I will be forever grateful I have been working on this for months, trying to figure this out, and have wondered why is wasn't working when finally found out there's drag in a simple game which turned out not to be so simple. If there is anything that I can help with I will most gladly try and help. Thank you for your time I really appreciate it.
