Compute the velocity of a free-falling parachutist using Euler's methor for the case where m=80 kg and C= 10kg/s. Perform the calculation from t=0 to 20s with step size of 1 s. Use an initial condition that the parachutist has an upward velocity of 20m/s at t=0. At t=10s, assume that the chute is instantaneously deployed so that the drag coefficient jumps to 50kg/s. I think there should be some negative signs when plugging the values in, but I'm not sure which one.
