The velocity of a falling parachutist is given by
gm
m² (1 - e-( #)²)
V =
where g =
9.81 m/s². For a parachutist with a drag coefficient
C = 15 kg/s, compute the mass m so that the velocity is
v = 40 m/s at t = 9 s. Use Newton-Raphson Method to
determine m in kg. Consider at least six (6) decimal places to your
computations. Criterion: |f (m)| < 0.00005
Hint: m is more than 70 kg
Write your answer on the space provided below and round-off your
final answer to two (2) decimal places.
