I haven't done anything Physics related in 2 years (highschool) and am trying to get back into being familiar with Physics, Science, and mathematical terms for an upcoming class.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A gazelle starts from rest and runs in a straight line 29° north of west. After 36s of running in this direction, the gazelle has a speed of 12 m/s. (a) What is the magnitude of the gazelle's average acceleration? Assuming that north and east are the positive directions, find the component of the horse's acceleration that points alone (b) the north - south line and (c) the east-west line.

2. Relevant equations

I know you have to do an initial equation by subtracting the animal's moving speed from the resting speed but from there I have no idea what to do. If someone could give me the correct formula, I can work the rest out myself.
