Homework Statement
A roller coaster is at the top of a slope moving very slowly. There are three lengths in this problem: h = 53 m is the height of the hill; D = 65 m is the length of the hill; L = 43 m is the length of the coaster. Derive an equation for the speed v1 when the first car reaches the bottom of the slope. (The hill has constant slope.) Derive an equation for the speed v2 when the last car reaches the bottom. What is the ratio v1/v2?
Homework Equations

The Attempt at a Solution
To be honest I don't really know where to start. I know how to solve this to find the velocity at the bottom of the hill if it were considered a point particle, but not for the things that the question is asking. So any advice or help would be greatly appreciated.
