(a) Give the vector representing the actual movement of

the boat.

(b) How fast is the boat going, relative to the ground?

(c) By what angle does the current push the boat off of

its due east course?

A - I don't I'm doing it right. I have 25i +10j + 26.9k

I used the Pythagorean theorem with a = 25 b = 10, and I solved for c.

b - I don't know how to deal with the southwest. It would be easy if the current was going in the opposite direction of the boat.

c- same. I don't know how to deal with the southwest direction.

Thanks!
