Is Momentum and Kinetic Energy Conserved in Collisions?

[Habibrobert]

Hello,

I am stuck on the last page of my physics post lab. The lab was on elastic, super elastic and inelastic collisions. The point of the lab is to see whether or not momentum and kinetic energy is conserved during each scenario.

I'm pretty sure that in the elastic and super elastic collisions momentum and kinetic energy is conserved.

I know that kinetic energy is not conserved in a inelastic collision.

Could someone please check my work and let me know if I am doing everything correct?

Many Thanks

Your numbers look really strange. Judging from the questions, you should have no numbers much above 1, and the Pf/Pi ratio should be close to 1. Maybe I misguess what these numbers represent. How about describing the experiment?
