Question

A boat’s velocity, measured in meters per second, is described by vector b =〈3,-4〉. In two or more complete sentences explain how to find the speed of the boat and the direction it is traveling in standard position. In your final answer, include all of your calculations.

Answer 1

S 36.87° E

Explanation:

It moves in a certain direction determined by

(y/x) = arctan

arctan (-4/3) 306.87° arctan (-4/3) arctan (-4/3) arctan (-4/3) arctan (-4/3) arctan (-4/

S 36.87° is another way of describing this travel direction.
