**[SOLVED] Angles and forces/normal force...**

1. A car coasts (engine off) up a 30 degree grade. If the speed of the car is 25 m/s at the bottom of the grade, what is the distance traveled by the car before it comes to rest?

2. Umm...I have no idea what equations are used in this problem. I know we were using A=Fnet/M and I also know that Fnet=Tcos(angle). I can't seen to find any equations that were given that include this angle.

3. The answer is 64 M. I just have no clue how to get this answer. Since it's asking for distance and it has a velocity I am completely thrown off.
