okay, there is a roller coaster with 2 hills.. this is what I know:
1st hill height: 40m
2nd hill height: 25m
mass of coaster: 500kg
I was asked to find out the PE at top of hill #1, I did that and got 196,000J
Now I have to findthe KE at the bottom of hill #1, as well as finding the velocity at various spots, how do I do this?
Thanks a LOT for the help in advance.
