Thank you!

I was just wondering if the momentum would be bigger for the golf ball before the collision than after.. if it was wouldn't that prove the conservation law false?

I have a question about the conservation of momentum. if a moving golf ball hits a bowling ball that's not moving, wouldn't the momentum be bigger than the momentum of the golf ball before the collision? THe velocity of the bowling ball would be very small... doesn't this violate the momentum law?

the more speed you need, the more fuel you need, so the more energy you need?

Ok, I have tried to rationalize this problem, but I am stuck, I don't even know how to start! I know it has to do with kinetic energy though. When a truck goes from rest to 30 miles per hour, it uses one ounce of fuel. HOw many ounces of fuel does it use when it goes from 30 miles per hour to...
