When launching a catapult physics is very much present. It starts with the angle that the catapult is at as well as its horizontal and vertical projectile. The horizontal acceleration will always be 0 m/s^2 and the vertical acceleration will be 9.81 m/s^2. The initial velocity and final velocity for the horizontal component will be the same and final velocity for the vertical component will be 0 m/s. Also the time for the horizontal and vertical component will be the same. Distance on the other hand for the vertical and horizontal component will be different. To find the horizontal and vertical component if it is not given to you, you can use the formulas Ay =Asinθ and Ax =Acosθ. Physics is most definitely present when shooting a catapult especially when solving using kinematic equations.
