% Define Variables
% Y(1) = Horizontal Displacement (x)
% Y(2) = Horiztonal Velocity (u)
% Y(3) = Vertical Displacement (y)
% Y(4) = Vertical Velocity (v)


%Declare constants
% g = gravity
% Cd = drag coefficient of baseball
g=9.81;
Cd=0.346;

dy= zeros (4,1); %define speed

%
dy(1)= Y(2); %horizontal velocity
dy(2)= -Cd*Y(2); %horizontal acceleration
dy(3)= Y(4); %vertical velocity
dy(4)= -g; % vertical acceleration
