I have a known potential energy, V, expression: V(x,y,z) = α·x + β·y2 + γ·z3 I'm given: @(0,0,0), v = v0 and then asked to find v at (1,1,1). I can determine v from Conservation of Energy: v2 = v02 - (2/m)·(α + β + γ)2 In general, what is the expression for the accelerations ax, ay, az? Do I find F from -∇V? If so, what's next (as far as finding the acceleration's x, y and z-components)? Thanks!
