Homework Statement
I have a roller coaster with 6 segments. i must find the speed, potential energy, and kinetic energy at the beggining and end of each segment that a marble rolls through.
Lets say that the marble is 8.47kg in mass, and i have one segment of the coaster having a distance of 0.39m.
How do i calculate the velocity, and kinetic energy with those two pieces of information only? Also, do i need to hae the angle of incline to answer these questions?
Homework Equations
Ek=1/2mv^2 Ep= mgD v=(root)[2Ek/m) w= Fapp x D
The Attempt at a Solution
i tried finding potential energy, and the work. but didnt know what to do after that.
