Yo Justin, you're smoking crack. Check this shit out:

 

a(t) = -32.2 m/s^2

v(t) = -32.2t + v0

x(t) = -16.1(t^2) + v0t + x0

 

v0 = 0 , x0 = 22.5ft, defining x to be the vertical axis and '0' to be at the ground level.

 

So.

-22.5=-16.1(t^2)

 

t=1.18216560936s

 

Substituting t into the equasion for v, we get

 

v(1.18216560936) = -32.2(1.18216560936) = -38.0657326214 ft/s

 

or 25.9539 mi/hr, if you prefer such arcane units.

 

hey dumbass...watch yer units...that would be 32.2 FT/s^2...not meters...

 

Grade for sloppiness: C-

 

Suck it!
