We're gonna do a project on elastic/inelastic collisions and we have to be able to demonstrate each type of collision IN A CREATIVE WAY. Here some things i was thinking:

for inelastic:
shooting an arrow at a target
shooting a dart at a target (if arrows are too expensive or whatever)
Using a toy gun to shoot a foam dart (Nerf gun)

Elastic Collisions:
Take two remote controlled cars and run them into each other with some action figures strapped on top just for fun.

Ok please give me some more ideas and be as creative as you can. thanks in advance

Additional Details

why wouldn't my car idea work for elastic ?

Isn't an elastic collision when something hits something and it goes back with the same kinetic energy? like a tennis ball hitting a tennis racket.

I understand that this is more of a statistics question, but there is no "Statistics" category.

Say some kind of machine is produced and numbered (serial number) and I encounter a couple of machines in the "field". How can I estimate the total production from the numbers encountered?

Is there literature on this?

I just plain don't get it...

Investors do not invest all of thier money in the investment predicted to be the best because it can be too risky. An investor holds shares in 3 independant companies, A, B, and C. An analyst predicts the probability of profit increases for each to be:
A - 0.70
B - 0.50
C - 0.65

a) If the analyst's prediction's are true what is the probability that all three companies will show a profit increase. Express to the nearest hundredth of one percent.

b)what is the probability at least one company will show a profit increase.Express to the nearest hundredth of one percent.


I am sure if someone could get me started on a) I will realize I am having a huge dumb moment and figure it out. Thank you in advance
