Matlab code or answers. thank you!

1.) Euler's Method / Parachute problem ( max11 Points) For the second-order drag model, compute the velocity of a free-falling parachutist using Euler's method for the case where m=80kg and cd=0.25kg/m. Calculate the velocity from t=0 to 6s with a step size of 2s. Use an initial condition that the parachutist has an upward velocity of 20m/s at t=0. At t=4s, assume that the chute is instantaneously deployed so that the drag coefficient jumps to 1.5kg/m. In this problem, define upward velocities as negative velocities
