9. Barnaby the ladybug is crawling along a spiral shaped tomato cage following the path r(t) = (cos(2nt), sin(2nt), 4v2at) for 2 S t - 9. (a) The density of the tomato cage is given by p(x, y, z) = 1/z. What is the mass of the tomato cage? (b) Suppose that a force F(x, y, z) = (2ry, x2, 1/z) is acting. Calculate the work against F required to move Barnaby from (1, 0, 8v27) to (1, 0, 36v/27)
