title: Simulink projectile motion with air resistance simulation
body: <p>I want to do Simulink model of projectile motion with air resistance.
  <img src="https://i.stack.imgur.com/dfbv9.jpg" alt="I have already done this">.</p>
  
  <p>X0 is the initial speed of x and Y0 is the initial speed of y. So the initial speed is V0 = 8 m/s. </p>
  
  <p>How do I considering the air resistance, weight, start height and the initial angel?
  Drag coefficient C = 0.01</p>
