... 2. Newton’s third second law states that the force a cannon exerts on a cannonball is equal and opposite to the force the cannonball exerts on the cannon. Does it follow that the impulse the cannon exerts on the cannonball is equal and opposite to the impulse the cannonball exerts on the cannon? ...

Momentum, Impulse, and Collisions
... Momentum for a System is Conserved • Momentum is ALWAYS conserved for a COMPLETE SYSTEM, you just have to look at a big enough system to see it correctly. – Not conserved for a single ball in the field of gravity – A ball falling is not a big enough system. You need to consider what is making it fa ...

MOMENTUM! - Bibb County Public School District
... In the first two sample problems, we dealt with a frictionless surface. We couldn’t simply conserve momentum if friction had been present because, as the proof on the last slide shows, there would be another force (friction) in addition to the contact forces. Friction wouldn’t cancel out, and it wou ...

... • A baseball of mass 0.15 kg has an initial velocity 0f -20 m/s (moving to the left) as it approaches a bat. It is hit straight back to the right and leaves the bat with a final velocity of +40 m/s. (a) Determine the impulse applied to the ball by the bat. (b) Assume that the time of contact is 1.6 ...
