For the second-order drag model (Eq. 1.8), compute the velocity of a free-falling parachutist using Euler’s method for the case where m = 80 kg and cd = 0.25 kg/m. Perform the calculation from t = 0 to 20 s with a step size of 1 s. Use an initial condition that the parachutist has an upward velocity of 20 m/s at t = 0. At t = 10 s, assume that the chute is instantaneously deployed so that the drag coefficient jumps to 1.5 kg/m.
