Could someone give me the first step? I know that I will eventually use delta x = vx x t, but what do I need to do before that?

**bobpursley**, Tuesday, November 6, 2007 at 3:52pmThe first step is the vertical equation, to determine the time in air.

Determine the vertical and horizontal components of the initial velocity.

Vertical equation.

Hfinal=Hinitial + Viv*t - 1/2 g t^2

solve for t, the time in air. Then work the horizontal equation.

dfinal=vih*t

t1 = Vsin(µ)/9.8.

h + 35 = 9.8t2^2/2---->t2

d = Vcos(µ)(t1 + t2)
