1. The problem statement, all variables and given/known data "You are investigating an accident where a 1500 kg car rolls down a hill with a slope of 8 degrees, a distance of 150 m (measured along the road) and hit a parked van. How fast was the car moving when it hit the van, assuming little friction?" 2. Relevant equations If I knew all of the equations, I would have most likely figured out the problem. Force= mass x acceleration K-work=velocity x impulse K-work= Force x distance 3. The attempt at a solution Now what I did so far was calculated the force of gravity pushing down on the car which is mass x gravity acceleration constant which I ended up getting 14,700 N. I then figured out using the 8 degrees and the force I just calculated, the force of the hypotenuse of the right angle I created. When I figured that all out I got some huge acceleration. Can someone please help me with this? I feel like it's so simple.
