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

    1. The problem statement, all variables and given/known data

    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.

    2. Relevant equations
    delta U=-∫F(x)*dx

    3. 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?
