Hi, I'm a first year engineering student and I'm having a hard time understanding this concept. How do you calculate acceleration an an incline plane? Currently I'm working on a problem that has a truck with a mass of 2430 kg traveling at a velocity of 85 mph up a ramp inclined from the x-axis at an angle of 15 degrees. The problem asks me to calculate the distance it will take the truck to stop, brakes and friction are not factors. I know that this is a vector problem and that I need to calculate the force of the truck and the force of gravity. My first problem is that I don't know the acceleration of the truck, only the velocity, is there a way to calculate the acceleration using the data I have provided? Any help would be much appreciated, currently I'm in over my head.
