# Consider a particle that moves in M = {(x, y, z) : 32 + 242 + 222 Rwith Vf = F.

Consider a particle that moves in

M = {(x, y, z) : 32 + 242 + 222 <4},

and is subject to the force field given by

F(x, y, z) = (1, -2z, -2).

(a) Show that F is conservative and find a potential for it, that is, a function f : R3 -> Rwith Vf = F.

(b) Use (a) to compute the work W (xx, y, z) done by F to move our particle from (-1, 1, 0) to a point (x, y, z) in M.

(c) Determine the maximum and minimum values of W (x, y, z) in M, listing all points at which those values occur.
