Question

Problem 2 (explain each codes please)

If more information if needed please let me know

1) % time vector

t=linspace(0,1,1000);

x = zeros(size(t));

y = zeros(size(t));

Meaning:

3)% loop to find the value of x and y for different values of time

for i=1:length(t)

x(i) = v*cos(angle_theta)*t(i);

y(i) = h+v*sin(angle_theta)*t(i)-(0.5*g*(t(i).^2));

end

Meaning:

4)% find the first index where y<=0 i.e the ball hits the ground

I = find(y<=0,1);

fprintf('The ball hits the ground at distance of %f meters\n',x(I));

Meaning:

5) plot(x,zeros(size(t)),'k--');

Meaning:
