The velocity of a falling parachutist is given by v = gm/c (1 e

The velocity υ of a falling parachutist is given by v = gm/c (1 – e ^{– (c/m)t}). Where g = 9.8 m/s². For a parachutist with a drag coefficient c = 15 kg/s, compute the mass m so that the velocity is υ = 35, m/s at t = 9 s. Use the false-position method to determine m to a level of ε_s = 0.1%.
