Dwight,
Don't think of it as a soccer problem, think of it as a force problem and=
add the vectors.
vector x direction =
y direction
V1 30.556 cos(45) 30.556=
sin(45)
V2 16.667 cos(180) 16.667 =
sin(180)
Vx =3D (V1x + V2x) =3D 4.94 m/s Vy =3D (V1y + V2y)=
=3D 21.61 m/s
V =3D (Vx^2 =3D Vy^2)^1/2 =3D 22.15 m/s
angle arctan (Vy/Vx) =3D 77.12 degrees
