Spaceship at Relativistic Speed

%% Spaceship at Relativistic Speed
% Determines the speed of the spacefhip in terms of the speed of light and
% how much time it takes to cook something in the oven

% Constants
c = 3.00*10^8;                  % [m/s] Speed of Light

% Inputs and Variables
L0 = input('Spaceship length at rest\n');
L = input('Spaceship length when moving\n');
t = input('Time for oven\n');

% Outputs and Equations
Beta = sqrt(1-(L/L0)^2);
T = t/sqrt(1-Beta^2);
fprintf('Speed of the spaceship: %.3f\nTime: %.3f Hours', Beta, T)
