Beacsue clay is usually of greater mass than rubber, I thought the glider would move left since the question involves momentum. Since the equation of momentum is p=mv, I thought the clay ball would cause the gilder to move left. -Rayna Patel
Both attended the same mass one sticks and one bounces. Critical Examples Spit ball example/ big fish little fish Tennis ball example.
So if the object bounce the one tracking to the right has a + p. And the one traveling to the left has a -p. So if the p was say +5 before it must be + 5 after in bouncing. The -p+ +p= 5. That means the +p > 5
This is another question where I had the correct answer and ended up changing it. I still do not understand the correct choice, though. It says the change in P is greater in the rubber ball than the clay ball. Is it because the rubber ball goes from a momentum, to no momentum, back to its original momentum where the clay ball just goes from its momentum to zero and it ends there? It is just confusing because the rubber ball starts with a momentum and in the final picture it goes back with the same momentum, where the clay ball goes from having a momentum to zero.

ReplyDeleteyou are ignoring the total momentum of the system...
Deletethe question is trying to figure out if you vcan apply the idea of momentum to the system...
make up #s to represent the momentum....
ReplyDeleteWrite the expression for the total momentum of the system. Before and After
set them equal.
compare
