We literally just covered this in my physics class last night. Thanks for the great timing OP. ðŸ™‚ Reply

Yes kids… This IS how you land two simultaneous artillery rounds on your target, doubling your kills. Reply

Reminds me of Tanks

Neat how quadratic equations have two roots.

Does every shot use the same amount of force on the object thrown?

We should have these plotted in a space-time diagram.

I would like to see this, but with air resistance added.

Looks like an experiment I did when I was 10 with a Nerf Football and my brother.
