% Projectile Motion – Project (v1):

%  Projectile Motion – Project (v1): Motion to Max Height
%  Governing Equations
%  x = x0 + V0x*t + 1/2*ax*t^2
%  y = y0 + V0y*t + 1/2*ay*t^2
%% Initial Conditions
x0 = 0
y0 = 10   % m
V0 = 15   % m/s
ax = 0
ay = -9.8  % m/s^2
theta = 70 % degrees
dt = 0.05  % s
%% Calculated and Derived Quantities
theta_rad = theta * pi/180
V0x = V0 * cos(theta_rad)
V0y = V0 * cos(theta_rad)
%% Create the Time Vector
t = 0 : 0.1 : 5
%%
x = x0 + (V0x*t) + (0.5*ax*t.^2)
y = y0 + (V0y*t) + (0.5*ay*t.^2)
%% Plot 
plot (x,y)
title (‘Trajectory of a Projectile’)
%% Use User Defined Input
%z = input (‘Enter a Title for the Graph(in single quotes)’)
plot (x,y), title (z)
z = ‘Trajectory of a Projectile’
plot (x,y), title (z2)
z2 = sprintf (‘Trajectory of a Projectile with V0=%f m/s and Angle %f degrees’, V0, theta)
title (z2)
