A cannonball fired from a long-barrel cannon will have a greater muzzle velocity because the cannonball receives a greater

Question

Quizplus · Accepted Answer

Muzzle velocity is directly proportional to the impulse imparted on the cannonball. Impulse is the product of force and time, and since the time of contact between the cannonball and the cannon is the same regardless of the length of the barrel, the longer barrel allows for a greater force to act on the cannonball, resulting in a greater impulse and muzzle velocity.
