**Henry**, Saturday, December 18, 2010 at 3:19pmVh = hor = 325cos340 + 40cos320,

Vh = 305 +30.6 = 335.6mph.

Vv = ver = 325sin340 + 40sin320,

Vv = -111.2 -25.7 = -136.9mph.

tanA = Vv/Vh = -136.9 / 335.6 = 0.4080,

A = - 22.2deg CW = 337.8 deg. CCW.

R = Vh / cosA = 335.6 / cos337.8 = 362.5mph @ 337.6 deg.
