X and Y coordinates (in m) to acceleration.

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

X and Y coordinates of a point are x = 2.2cos(1.2t) and y = 2.2sin(1.2t) (both in m) where t is the time. What is the magnitude of acceleration (in m/s/s).

2. Relevant equations


3. The attempt at a solution

I don't know where to begin with this question. Any suggestions would be helpful.
The equations you mentioned are actually irrelevant and they don't help at all. What you really need is to use the basic definition of acceleration. First you find acceleration in x and y direction and then use Pythagorean theorem to find the magnitude (acceleration is a vector!).
Thank you, I wasn't sure so I posted the equations I have been using for all of my other problems.

I was able to find the correct answer using this help. Thanks a lot!
