and it's all because i'm listening to early 70s prog rock, i swear.

i mean, look at their name. how can they NOT help you understand science.

*insert dance of understanding physics*

uf= (m-M)ui/(m+M) + 2mvi/(m+M)

vf= 2mui/(m+M) + (M-m)vi/(m+M)

right?

and Fg= G (m1m2)/r2

and p=mv
and FnetDeltaT=mdeltav
and and KE=1/2 mv2
and is there anything else that I really need to know?

OH RIGHT

Vcm= (mui + Mvi)/(m+M)

and Vobjcm=Vobjlab-Vcmlab

I think the last one might not be right but I don't know.

yeah, you don't want to forget the center of mass stuff. it's not that hard, but still.

and don't forget the uniform circular motion and gravity equations.

Gmm/r2, a=v2/r, v=2pir/T

Yes, well, FUCK YOU.
