A particle is moving along the x-axis subject to the potential energy function

[AD_3]

Homework Statement

A particle is moving along the x-axis subject to the potential energy function U(x) = 1/ x + x2 + x – 1. Determine the x-component of the net force on the particle at the coordinate x = 3.67 m.

Homework Equations

delta U=-∫F(x)*dx

The Attempt at a Solution

I tried to take the integral of the given function from 0 to 3.67 but that didn't work and I tried plugging in the the distance into the equation and that didn't work either.

You need the force. How do you get force from potential?
