Newton`s 2nd Law and Momentum Problems
... 10. When a cannon is fired, Newton’s 3rd Law states that there will be an equal and opposite reaction, and momentum will be conserved. If a 20-Kg cannon ball is fired at a velocity of 980 m/s, what will the rearward velocity of a 1500-Kg cannon be if the cannon is mounted on wheels and allowed to ro ...
