This is seems like an easy question

    This is seems like an easy question....

    1. The problem statement, all variables and given/known data
    A single conservative force acts on a 5.00 kg particle. The equation Fx = (2x + 4) N describes this force, where x is in meters. As the particle moves along the x axis from x = 2.20 m to x = 6.60 m.

    Calculate the change in the potential energy of the system

    2. Relevant equations

    3. The attempt at a solution

    Since it just only involves horizontally, I thought the Potential Energy would be zero, but it's telling me it's wrong.

    I think you should look up relevant equations, like how work done by a conservative force F will be W = -ΔU where ΔU is the change in the potential energy. So W = Fd (force*distance) or W = Fdcosθ...
