1. A single conservative force acting on a particle within a system varies as = (− Ax + Bx6)ihat N, where A and B are constants, is in newtons, and x is in meters. (a) Calculate the potential energy function U(x) associated with this force, taking U = 0 at x = 0. (b) Find the change in potential energy and change in kinetic energy as the particle moves from x = 1.30 m to x = 3.60 m. 2. I got Ax^2/2 - b^7/2 but it was wrong so I'm really confused on how to go about this problem Thanks!!
