The potential energy phi , in joule, of a particle of mass 1 kg, moving in the x-y plane, obeys law phi = 3x + 4y, where (x, y) are the coordinates of the particle in metre. If the particle is at rest at (6, 4) 4 in joule moving in the x-y plane obeys law phi = 3x + 4y of a particle of mass 1 kg The potential energy phi where x y) are the coordinates of the particle in metre.
