a skier is accelerating down a 30.0 degrees hill at 3.10 m/s^2. What is the vertical component of her acceleration?(adsbygoogle = window.adsbygoogle || []).push({});

I did 3.10 m/s^2 *sin(30) and got -1.55 m/s^2, but as usual, my answer is wrong.... The box for the answer looks like this: ____m/s2 (downward)... am I wrong because I put in the negative sign?
