Finally !!!

I already miss Spamton ...

I figured it out, but it’s still too many added extra steps. Just subtract the final and initial velocity for each cart and see if the number is the same but with opposite signs. Why did they complicate it?

I hate this lab report so much - I don’t even understand how to do it?

The question is if velocity changes depending on the collision type (two carts hit each other). They want us to calculate momentum then make a BAR graph and add error bars to see if the initial and final fall into each other’s uncertainty range of 10%.

That doesn’t make sense !!! Plus the example BAR graph only shows ONE cart’s momentums ! There’s TWO carts. It’s a system. What did you do to the second cart ?

All you SHOULD have to do is subtract the final and initial velocity of both carts and see if the number is more or less the same - because the carts collide by travelling in opposite directions.

The one in blue is actually positive, I forgot to change the sign to account for the coordinate plane of the system.

What am I supposed to do ? Apparently leave off a cart, but that doesn’t make sense - it’s a system of two. Also why bother calculating momentum, it just makes it more complicated. It’s sue tomorrow before midnight - should I email the teacher and say my way makes more sense (to me) and hopefully be allowed to turn it in like this ?

This doesn’t look right (how they want me to do it):

Also we were told by the substitute to do as many collision types as possible, but I saw other classmates just do three types instead of six. So it’s more work for me and I really just want to delete the extra three.
