(a) At what angle must you point the jet ski if your velocity relative to the ground is to be perpendicular to the shore of the river?

(b) If you increase the speed of the jet ski relative to the water, does the angle in part (a) increase, decrease, or stay the same?

If the velocity is perpendicular, wouldn't the angle be 90degrees? That seems too easy; any help?

The upstream velocity is 18sinTheta. That has to equal the stream velocity, right? Solve for Theta
