Motion in a Fluid When a heavy body B of density ρB and volume V is immersed in a fluid of density ρF, the weight W of the body would be

(a) Show that we may define the gravitational acceleration as g = g (1 - ρF /ρB).
(b) Derive the equation of the path of a projectile in the fluid.
(c) Assume ρF = ρe-z and derive the equation of the path of a projectile in the fluid.
