Physics Game Ok, so here are the rules:
-Keep the questions very basic (PHYS 101 & 102); this is, afterall, a computer forum.
-Wait for confirmation that your answer is correct before posting your question.
-If 24 hours passes and still no confirmation, post a new question to keep the game going.
** Please follow the rules! **
I'll start:
Question:
A car (mass = 1100kg) is traveling at 32 m/s when it collides head-on with a SUV (mass = 2500kg) traveling in the opposite direction. In the collision, the two vehicles come to a halt. At what speed was the SUV traveling?

It is practically impossible to teach good programming style to students that have had prior exposure to Basic; as potential programmers they are mentally mutilated beyond hope of regeneration.

That depends: did the passengers come to a halt too, or did one or more of them fly out the windshield?

Does that even matter?
I am nothing special; of this I am sure. I am a common man with common thoughts, and I’ve led a common life. There are no monuments dedicated to me and my name will soon be forgotten, but I’ve loved another with all my heart and soul, and to me, this has always been enough. -The Notebook

The answer, of course, is 14.08 m/s in the opposite direction of the first car.

You're right... I'm talking to Duki on the phone and he said you are correct.

yay! My question is:
The position vector of a particle of mass 3kg is given by r(vector)= 4i+3t^2j, where r is in meters and t is in seconds. Determine the angular momentum and torque acting on the particle about the origin.

If you were worried about details, it would matter. The passengers were part of the energy system, and stopping them would require energy as well. If passengers from one vehicle were to continue flying through the windshield, it would change the amount of energy involved in the collision, and would change the result a bit.
