P#3. The velocity v of a falling parachutist is given by

where . For a parachutist with a drag coefficient c = 15 kg/s [motion resistance due to air], compute its mass m so that the velocity is v = 35 m/s at t = 9 s. Use either the bisection method (no Calculus I yet) or the Newtons method (Calculus I) codes developed in P#1 or P#2 to determine m to an error level of = 0.1%. Note that the above equation is expressed as:

(I need this in Matlab code, Thank you)
