## Homework Statement

Snoopy is running to his doghouse at 3.0 m/s [N 15° E] for 35 s. Charlie has a bone and calls his dog back. Snoopy immediately turns around and runs towards Charlie at 4.5 m/s [S 45° W] for 30 s. Find Snoopy's displacement.

## Homework Equations

dt = d1 + d2

d1=d

_{1x}+ d

_{1y}& d2=d

_{2x}+ d

_{2y}

d

_{1x}= V

_{1x}/t

## The Attempt at a Solution

Ok so I've started off with the components. N, E (+) and W, S (-)

V

_{1x}= (3.0)(sin15) & V

_{1y}= (3.0)(cos15)

V

_{2x}= (-4.5)(cos45) & V

_{2y}= (-4.5)(sin 45)

d

_{1x}= V

_{1x}/t

= (3.0)(sin15)/35

= 0.022m

d

_{1y}= V

_{1y}/t

= (3.0)(cos75)/35

= 0.083m

Therefore d1=0.022+0.083 = 0.11m...

I did the same thing for d2, splitting it up into its component parts. I know that after this I have to use d1, d2 and dr in the pythagorean theorem to find magnitude and then find the vector direction with the tan ratio. I'm just wondering if so far I am on the right track
