Question

MATLAB Program Problem A projectile is shot at an angle of 50 degrees with respect to the horizontal at a velocity of 200 m/s. Earth's gravity is 9.81 m/s 2. Take the variable x as the range and y as the altitude. Create a MATLAB plot, which plots that trajectory. Now, assume the terrain slopes up by 1 m in y for every 10 m in x. On the same axis, plot the line of the terrain in a different color.

Answer 1

MATLAB Code

syms t;

x = t * 200 * cosd(50);

y = t * 200 * sind(50) - 0.5 * 9.81 * t^2;

ezplot(x, y);

hold on;

x1 = 200 * cosd(50) * t;

y1 = 200 * cosd(50) * t / 10;

ezplot(x1, y1, '--');

hold off;
