Homework Statement
I have started my extended essay for the IB, My REsearch Question is "How does air resistance affect the projectile motion of sports balls?" i am collecting data by video taping the throws and measuring where the ball is in every frame. My supervisor tells me that i have to have and equation so that i can see the difference between the actual throw and the throw without air resistance, i don't now how to get that equation.
Homework Equations
v2 = u2 + 2as, S = ut + 1/2at2, v = u + at, d = vt
The Attempt at a Solution
I tried to generate a best fit equation of all the values collected, and then a best fit equation for the first values (since those values are the least affected by air resistance) and compare both equation's positive x-intercept
