Homework Statement
A train of mass 2.4x10^6kg enters a 5km stretch of track with a vertical rise of 40m at a s speed of 1.0m/s and leaves at 3.0m/s. Assuming that frictional drag is negligible, find:
a) Each term of the equation Win = delta K + delta U + Wout
Homework Equations
Delta K = 1/2mvf^2 - 1/2mvi^2
Delta U = mghf - mghi
Wout = work removed from the system such as air drag.
Win = not sure??
The Attempt at a Solution
I found Wout and that's equal to 0.
I found Delta K. Not too sure if I used the right velocities. Final velocity, i used 3.0m's and inital velocity, i used 1.0m/s.
I found Delta U, with the final height being 40m and the initial height being 0m.
Am i doing these correctly? Can someone guide me please?
