1) Suppose you catch a baseball and then someone invites you to catch a bowling ball with either the same momentum or the same kinetic energy as the baseball, which would you choose?
(I think kinetic energy because the total work required to stop the baseball is 1/2mv^2 and its pretty easy to catch a base ball...ie doesnt require much work) I'm not really understanding the concept of momentum so I could be very wrong.
2) When rain falls from the sky, what happens to its momentum? Is your answer valid with newtons famous apple?
(I think since P = mv that the velocity goes to zero when it hits so momentum must go to zero, and I think this must also hold true for newtons famous apple)
3)When a large heavy truck colides with a small passenger car, the people in the car are more likely to be injured than the driver of the truck, why is this?
(I dont know how to explain this one, I dont really understand the concept of momentum so I dont know how to explain it, this question says nothing about mass or velocities of the car & truck, i dont know what to say about this)
