(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A motorist drives south at 20m/s for 3min, then turns west and travels at 25m/s for 2min, and finally travels northwest at 30m/s for 1min. For this 6min trip, find:

a) the total vector displacement

b) the average speed

c) average velocity

let the positive x axis point east

2. Relevant equations

Vs = d/delta t

Vave= delta x/delta t

3. The attempt at a solution

i converted the mins to seconds, getting

south = 3600m

west = 3000m

northwest = 1800m

im getting confused because displacement is not the same as distance so i cant just add all 3 values together

for average speed i for 8400/6min = 23.3m/s

and im not sure how to find the change in x for average velocity..

please help! thank you! =]
