Question

help @YouSir

Answer 1

Suppose the total momentum of two masses before a collision is 100 kg m/s. What is the total momentum of the two masses after they collide?

1. 0 kg m/s
2. 50 kg m/s
3. 100 kg m/s
5. 200 kg m/s <--

Answer 2

@sasogeek

Answer 3

do you know about the law of conservation of momentum?

Answer 4

Yes

Answer 5

you should know the answer then. it's rather obvious if you know the law :)

Answer 6

@sasogeek is it 200 kg m/s

Answer 7

yes you are right :)

Answer 8

Can you help with a few more please??

Answer 9

yea sure

Answer 10

okay thank you

Answer 11

np

Answer 12

if the momentum before is 100 kg m/s, why would it be 200 kg m/s after?

Answer 13

if before = after
why would 100 = 200?
