Phython 3.7

This is the question. I have figured out how to create the calculation but am unsure how to put in the upward velocity of 20 m/s at t=0. I am also unsure how to put in when the shoot opens at t=10 with a drag coefficient c = 60 kg/s. Please help, and I need help graphing the curve. The equation for the problem is: where is the step size.

Here is my code now.

Compute the velocity of a parachutist using Euler's method for the case where m= 80 kg and c = 10 kg/s (simpler model used in P1). 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=0 [w(0) = -20]. At t = 10 s, assume that the chute is instantaneously deployed so that the drag coefficient jumps to 60 kg/s.
