**drwls**, Wednesday, February 6, 2013 at 9:56amLet t be the time of flight

Vcos32*t = 8.2

Vsin32*t -4.9 t^2 = 0.2

0.848 V*t = 8.2

0.530 V*t -4.9 t^2 = 0.2

First eliminate V by substitution and solve the resulting equation for t.

5.125 -4.9t^2 = 0.2

4.9t^2 = 4.925

t = 1.003 s

V = 8.2/(.848*1.003) = 9.64 m/s
