I believe it doesn't apply because there is no change in the y direction, as the carts are going along parallel, level tracks. Basically in the x-y coordinate plane, the two tracks would just be moving to the right, or along the positive x-axis. I told my professor that the heavier cart would...

Okay, after talking with my professor quickly he hinted that to actually solve the problem, i need to use conservation of momentum equations and that since the motion is along the x-axis (which i forgot to include in my explanation >_<), the potential energy equation isn't necessarily true :(...

Thank you! I had thought about using Energy methods but was unsure how to express it; how would i go about explaining that in an expression? My thoughts were: PEf + KEf = PEi + KEi 0 + 1/2(Mcart+Msnow)*Vf^2 = (MCart + Msnow)*(Gravity)*(L) + 0 Edit: After looking at it, doesn't the change in...

Homework Statement Hello all, I was given a problem which states that there are two identical mining carts, A and B, traveling down a distance L with equal velocities on two identical tracks. There is an identical man in each cart. As the carts travel, it begins to snow, which in turn...
