1. The problem statement, all variables and given/known data A single conservative force acting on a particle varies as Fvec = (-Ax + Bx5)i-hat N, where A and B are constants and x is in meters. Accurately round coefficients to three significant figures. (a) Calculate the potential energy function U(x) associated with this force, taking U = 0 at x = 0. (Use A, B, and x as appropriate.) U = ____________ (b) Find the change in potential energy and change in kinetic energy as the particle moves from x = 1.20 m to x = 3.80 m. (Use A, B, and x as appropriate.) ΔU = ____________ ΔK = ____________ 2. Relevant equations Not sure if there are relevant equations but PE = mgh 3. The attempt at a solution I really have never been this confused about a physics problem... I think the answer needs to be in an equation form? Im really not sure on this one guys, I tried to understand it, its just not coming to me. I did all the rest of the hw completely fine other than this one.
