when i drew it out first i drew out the east ward vector then the south one, and the resultant vector connecting the two allows me to use Pythagorean therom so no components were needed to find the resultant velocity, the east velocity and south velocity are at right angles to one another
alright so here's a pretty straight forward question asking to find the avg acceleration:
A car with a velocity of 25m/s [E] changes its velocity to 25 m/s [s] in 15s. Calculate
avg acceleration.
So i drew out the vector diagram, found the resultant velocity and solved for the avg...
