Homework Statement
The potential energy function for a system of particles is given by
U(x) = −4x^3 + 3x^2 + 8x,
where x is the position of one particle in the system.
(a) Determine the force Fx on the particle as a function of x.
Homework Equations
du/dx[U(x)] = Fx
The Attempt at a Solution
-12x^2+6x+8
webassign says this is wrong, what am I missing? Just did a problem like this where I was given the potential energy equation and had to find the force. In that case there was both x and y forces and had to take partial derivatives of each. This is frustrating me :(
