**Damon**, Wednesday, May 5, 2010 at 4:10amcurrent toward -y

We want to go in +x direction

steer at angle T up from x axis

components toward x

Vx = 4 cos T

components toward y

Vy = 4 sin T - 2

we want Vy = 0

so

2 = 4 sin T

sin T = 1/2

T = 30 degrees or in compass heading

30 degrees North of East = 60 degrees true
