I'm a bit stumped on the following, as I'm not sure how to distinguish between the following. Thanks to all those who shed some light.
A bug and a windshield of a fast moving car collide. Indicate and explain whether each statement is true or false.
a. The forces of impact on the bug and the windshield are the same size.
True? I suppose because of Newton's third law the force would be indentical.
b. The impulse on the bug and the car are the same size.
I'm a bit confused. I know FxT=Impulse=Change In Momentum. I would suppose that the big's momentum loss would be greater, but I'm only speaking from a practical/obvious POV.
c. The change in speed of the bug and the car is the same
Falso. Perhaps their related somehow, but I know that's false.
d. The changes in momentum of the bug and the car are the same size?
I would say true, because wouldn't the system after the collision have to somehow equal the momentum of the two separate systems before it? I assume this could only be achieved if the momentum's were related.
Thank you to all
