1. time to blue max ... v / g
red vel @ blu max ... v - g t
ave red vel ... (2 v - g t) / 2
red hgt ... (ave vel) * t
2. blu ... time up = time down
red vel @ blu impact
... v - g(blu flight time)
red vel @ blu max ... v - g t
ave red vel ... (2 v - g t) / 2
red hgt ... (ave vel) * t
2. blu ... time up = time down
red vel @ blu impact
... v - g(blu flight time)
