Question 1 For the second-order drag model: dt = g-mv 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 o. At t 10 s, assume that a parachute is instantaneously deployed so that the drag coefficient jumps to 1.5 kg/m. (Round the final answers to four decimal places.) Present your answer in the form of a table of calculated values and a plot. Show details of your work for the first three calculations. MATLAB or Excel can be used to calculate the values for the table
