t1 = 0.667, t2 = 0.67 represents collision time of 0.03 s
t3 = 1.033, t4 = 1.036  represents collision time of 0.03 s
F1x = -2420, F1y = 500 are required values trial and error determined for model to fit based on delta t = 0.03
F2x = 220, F2y = 3500 are required values trial and error determined for model to fit
fx = if(t<t1,0,if(t<t2,-2420,if(t<t3,0,if(t<t4,220,0)))) =if(t<t1,0,if(t<t2,F1x,if(t<t3,0,if(t<t4,F2x,0))))
fy = if(t<t1,-m*g,if(t<t2,500,if(t<t3,-m*g,if(t<t4,3500,-m*g)))) = if(t<t1,-m*g,if(t<t2,F1y,if(t<t3,-m*g,if(t<t4,F2y,-m*g))))
