Homework Statement
A small block with mass 0.0400 kg is moving in the xy-plane. The net force on the block is described by the potential-energy function U(x, y) = (5.80 J/m2)x2-(3.60 J/m3)y3. What are the magnitude and direction of the acceleration of the block when it is at the point (x =...
I think I see what you mean. You're saying simply just to take 1/2 kx2: 1/2(4000N/m)(-0.375)2, which yields 281.25 J or roughly 281J?
From there, I know that there's 0 velocity at the instant of release, so K1 is 0. Total work done is simply the kinetic energy K2, which is equal to 281J...
I accidentally posted over in general questions before seeing that wasn't the proper place for this type of question. I'm not looking for the answer, as I have that available. I'm just trying to understand part of the process here.
