Question 2 A skydiver's vertical velocity is governed by dv m - dt = mg - Kv2 where, m is the mass of the skydiver, g is gravitational acceleration, and K is the skydiver's coefficient of drag. (i) If the skydiver leaves his/ her aero plane at time t =0 with zero vertical velocity, find the vertical velocity equation, v. (9 marks) (ii) Compute the time that the skydiver reaches quarter of his/her final velocity. (5 marks) (iii) Solve the equation of v(t) assuming that you are the skydiver, g = 9.8m/s, and K = 110kg/s. Then, make a plot of the vertical velocity equation, v as a function of time, t for 0 S t
