what do you think?

Answer 2

A

Answer 3

did you think about momentum when you came to this conclusion?

Answer 4

I'm lost on this question idk

Answer 5

they are running in opposite directions. direction really matters when it comes to calculating momentum.

Answer 6

momenta cancel out when the directions are opposite, so you need net figure.

Answer 7

So its d

Answer 8

are you telling me or asking me?

that's the mind set.

Answer 9

Asking

let's toss a coin.

Answer 12

or just finish it correctly

Answer 13

I'll go with c

Answer 14

as long as you are sure.

Answer 15

momentum = p = mass * velocity
