need help with this question in Matlab please, thanks

A body of mass m falling under the action of gravity experiences drag, and so it will eventually approach a maximum speed. This maximum speed is called the terminal velocity vr, and can be calculated as mg VT = k 9.81 m/s? is the acceleration due to gravity, and k is a parameter for the drag force (k won't need this). The distance yr where a fraction n of the terminal velocity occurs is given by where g 0.5capA, but you m mg 2k" - In YT = – k(nvž) bu where n is a fractional factor of the terminal velocity ranging from 0-1 (exclusive). a) Write a function file that accepts the mass m, the drag parameter k and fractional factor the terminal velocity vr and the distance yt as outputs. as inputs, and provides b) A group of 7 people, each with equally-spaced mass values between 50kg and 100kg and a k value of 0.12kg/m jumps off a plane in a skydiving activity. Determine vr and yr of each person for n = 0.9.
