Develop a EXCEL VBA 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 $=79\mathrm{.}3$ kg and c $=9\mathrm{.}6$ kg$/$s$.$ Perform the calculation from t $=0$ to $20$ s with a

step size of $2$ s$.$ Use an initial condition that the parachutist has an upward

velocity of $9$ m$/$s at t $=0.$
