applied maths

grrrrrrrrrr

A question that seems to come up a bit and could someone answer it please as it does give an adequate answer in the book.

'State the laws governing oblique collisons'


Thanks

felic

I didnt do applied maths but I found this website that might help u..

Thanks, I dont think thats adequate though!

But thanks!

I don't think questions of that nature would come up on the HL Paper. OL possibly, but it's unusual to get asked theory on the HL paper, especially in the Collisions question.

Look up the marking scheme for the year it was asked, it should say there.

the two laws that govern oblique collisions are:
NEL: Newton's experimental Law which states that
-e = (difference of final vels)/(difference of inital vels)
where e is the coeff of restitution between the 2 bodies in question

PCM: Principal of Cons of Mom which states that
in the absence of an unbalanced external force, the total momentum before the collision is equal to the total momentum after the collision.

Also, for oblique collisions, NEL only applies to the i-velocities. The j-velocities remain unchanged. This assumes that you take the i-axis to be along the line joining the two centres at impact.

jomama

In fact, NEL applies to both components of the velocity, but since the j-components are unchanged they cancel eachother out. So, for simplicity, I would still use my definitions, and you are covered.
