You have a boat that is capable of moving at 11.8 m/s through still water. You wish to cross a river that flows due south at 5.4 m/s. At what numerical compass heading must you pilot your boat so that you will reach a destination that is due east of your current position?

Answer 1

cos (heading) = 5.4/11.8

Answer 2

Vb - 5.4i = 11.8.
Vb = 11.8 + 5.4i = 13m/s[24.6o] N. of E.
= Compass heading.

9-5.4i) =
