QUESTION
The force acting on an object is given by Fx = a/x2. At x = 5.1 m, the force is known to point in the −x direction and have a magnitude of 28 N. Determine the potential energy associated with this force as a function of x, assuming we assign a reference value of -9 J at x = 2.3 m for the potential energy.U(x) =________ J
