Chapter 2, Problem 24P

Develop a well-structured program to compute the velocity of a parachutist as a function of time using Euler's method. Test your program for the case where $m=80\text{kg and }c=10$kg/s. Perform the calculation from $t=0\text{ to 20}$ s with a step size of 2 s. Use an initial condition that the parachutist has an upward velocity of 20 m/s at $t=0.\text{ At }t=10$ s, assume that the parachute is instantaneously deployed so that the drag coefficient jumps to 50 kg/s.
