Homework Help: Physics

Posted by HELP PLEASE on Sunday, October 14, 2012 at 2:17pm.

You are riding on a jet ski directed at an angle upstream on a river flowing with a speed of 2.8 m/s. If your velocity relative to the ground is 8.9 m/s at an angle of 26.0° upstream, what is the speed of the jet ski relative to the water? (Note: Angles are measured relative to the x axis.)

Need help solving:
I have this so far by i could be wrong

Vy = 8.9 sin 26° =
Vx= 8.9 cos 26° + 2.8 =

V = sqrt(Vy^2 + Vx^2)
