Q#2. The terminal velocity of skydiver depends on many factors, including their weight,
their body position as they fall, the density of air, the terminal velocity (vt) is given by:
Vt=2mg/raؤ
where m is skydivers mass, g=9.8m/sec2 , a= 0.75 for a moderate person, r=1.2 the
atmospheric density, and cd =1 is the skydivers coefficient of drag.
(a) write a matlab user defined function that accept m to compute vt
(b) write a matlab program that prompts the user to enter the values of m, by using the
function you defined in part (a). (ask the user to enter value > 40kg)
(c) plot vt for the range of m=[40:0.1:the user prompt input], label the x-axis "skydiver
mass in kg", and y- axis "terminal velocity vt in m/s"
(d) use the function you defined in part (a) in order to find minimum vt in the range of m
between 50 to 500kg.
