3. Suppose an object at a given location has potential energy of U; = 10 J and kinetic energy of K; = 20 J. Assuming there are no other outside forces acting on the object, how much kinetic energy does the object have when its potential energy is Uf = 40 J. (a) Kf = -10 J %3D (b) Kf = 20 J %3D (c) Kf = 50 J (d) This situation cannot be achieved.
