**Henry**, Friday, April 13, 2012 at 5:05pmI am assuming the time of impact is the time to strike ground.

Given: Vo = 88Ft/s @ 35 Deg. = Initial velocity.

Xo = 88*cos35 = 72.1 Ft/s = Hor. comp.

Yo = 88*sin35 = 50.5 Ft/s = Ver. comp.

Tr = (Y-Yo)g = (0-50.5)/ -32 = 1.58 s =

Rise time.

Tf = Tr = 1.58 s. = Fall time.

Tr + Tf = 1.58 + 1.58 = 3.16 s. = Time

in flight or time of impact.
