those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly. 3. For the same force‚ why does a long rifle impart more speed to a bullet than a short pistol? The long barrel means that the force of the expanding gases from the gunpowder is able to push for more time on the bullet (since the push will continue as long as the bullet is in the barrel). Impulse = (Applied Force)*(time) 4. When you are in the way of a moving object and a collision is sure to occur‚ are you
