**Damon**, Saturday, June 28, 2014 at 5:06pmYou add the final VERTICAL velocity and the constant horizontal velocity as vectors. You can find the direction with trig if you wish, but the vector components imply direction as well as magnitude. For example

V = u i + v j

where u is the horizontal velocity component

v is the vertical velocity component

i is the unit vector in the x (horizontal) direction

j is the unit vector up
