function v = skydiver_func1(m,g,c,t)
% Function to calculate skydiver falling speed
% for specified parameter values and time vector
% using the analytic solution.
%
% Inputs:  mass m (kg)
%          gravity g (m/s^2)
%          drag coefficient c (kg/m)
%          time vector (s)
%
% Outputs: falling speed vector v (m/s)

v = sqrt(m*g/c)*tanh(sqrt(g*c/m)*t);
