Explanation:
Question is missing. Found it on google:
"<em>What is the magnitude of the final momentum of the bowling pin if it has a mass of 1.5 kg</em>?"
Solution:
we can solve this problem by using the law of conservation of momentum. In fact, the total momentum of the system must be conserved, so we can write:
where
is the momentum of the ball before the collision
is the momentum of the pin before the collision (zero because the pin is stationary)
is the momentum of the ball after the collision
is the momentum of the pin after the collision
Solving the equation for , we find:
