Final answer:
Newton's 2nd Law explains the motion and forces involved in launching a projectile with a catapult or trebuchet. when the pulling arm of the device is released, the stored potential energy is converted into kinetic energy, causing the projectile to accelerate and be launched.
Step-by-step explanation:
Newton's 2nd Law relates to a catapult/trebuchet as it helps explain the motion and forces involved in launching a projectile. According to Newton's 2nd Law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In the case of a catapult or trebuchet, when the pulling arm of the device is released, the stored potential energy is converted into kinetic energy, causing the projectile to accelerate and be launched.
