Matlab 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. pay attention to altitude, range and the terrain. you!
