I have attempted this problem on my own on paper now. Before I was just thinking out loud I suppose. I went ahead and switched the direction of our coordinate axis so that the GREEN car moves in the positive x-direction, beginning at x=0, and the RED car is now at x=230m and moving to the left...

s in this case is displacement (should be x since you mentioned the x-axis), and u is velocity (usually written as a v) with a, and t representing acceleration and time respectively. The key to the problem is determining the times involved. For instance, at 24.0 km/h, the red car travels 45.5 m...

Homework Statement Hello. I am attempting to evaluate the classical action of a harmonic oscillator by using the Euler-Lagrange equations. Homework Equations The Lagrangian for such an oscillator is $$ L=(1/2)m(\dot{x}^2-\omega^2 x^2) $$ This is easy enough to solve for. The classical action...
