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 in 15s. Calculate
avg acceleration.
So i drew out the vector diagram, found the resultant velocity and solved for the avg acceleration. My answer was right but the direction was wrong. My answer was 2.4 m/s^2 [45 degrees south of east ]
however, the books answer is 2.4 m/s^2 [45 degrees S of W] Can anyone explain to me
why it is south of WEST and not East?
