Here is the question, need solution with detailed explanation.
Textbook: Numerical Methods for Engineers, 7th edition, question 1.5
Compute the velocity of a free-falling parachutist using Euler’s
method for the case where m 5 80 kg and c 5 10 kg/s. Perform the
calculation from t 5 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 5 0. At t 5 10 s, assume that the chute is instantaneously deployed
so that the drag coeffi cient jumps to 60 kg/s.
