Answer:
+17 kg m/s
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:
To find the average (aka mean) of a group of numbers, all we need to do is add them up then divide that number by how many numbers we started with
23 + 21 + 24 + 22 = 90
90 ÷ 4 = 22.5
Therefore, the average distance the book traveled on ice is 22.5 cm
15 + 18 + 16 + 17 = 66
66 ÷ 4 = 16.5
Therefore, the average distance the book traveled on concrete is 16.5 cm
In conclusion, the average distance the book traveled on ice is greater than the average distance the book traveled on concrete
Hope this helps you
