# In what direction is the scout's position relative to the campsite?

Okay, the first one I have no clue how to set up or start, so a hunt would be nice. The second one, I figured out (a) but can''t seem to get (b) or (c) and want to know what I'm doing wrong.

## Homework Statement

A scout walks 5 km due east from camp, then turns left and walks 4.5 km along the arc of a circle centered at the campsite, and finally walks 3 km directly toward the camp.
(a) How far is the scout from camp at the end of his walk?
___ km

(b) In what direction is the scout's position relative to the campsite?
___ ° (clockwise from north)

(c) What is the ratio of the final magnitude of the displacement to the total distance walked?
___

A particle moves in the xy plane with constant acceleration. At time zero, the particle is at x = 3.0 m, y = 6.0 m, and has velocity v = 1.0 m/s i + 7.0 m/s j. The acceleration is given by the vector a = 9.0 m/s i + -1 m/s j.

What is the velocity vector at t=3.0s
I got (28 m/s) i+ (4 m/s) j

What is the position vector at t=5.0s

What is the magnitude and direction of the position vector
