**drwls**, Saturday, November 24, 2012 at 7:01am(a) Write two independent equations for the time of flight T, based upon (1) the initial vertical component and (2) the horizontal component of initial velocity, Vo. Set the two times equal to eliminate T, and then solve for Vo

(b) Vx = Vo cos60

Vy (at impact) = Vo*sin60 -g*T

Fot T, use 80 ft/(Vo*cos60)
