Which of the following has the least momentum?

a. 0.05 kg mass moving at 200 m/s

b. 10.0 kg mass moving at 30 m/s

c. 200 kg mass moving at 2 m/s

d. 3000 kg mass moving at 0.2 m/s

I mean, IMO, you shouldn't mark this off-topic, because science is realted to math, not as good as science as math, so......................can't answer! Sorry! ^m^ whymenotsmart, it should be a....................

Well actually this forum is for math but science is ok so should be marked as off topic

 

but then physics is very close to math so that's a matter of debate

yeah its a bit of debate, but I think it could fit either place, but I feel like it would go more towards the off topic since this is a science question.

The formula is momentum = m*v so

 

we plug numbers in and get

 

100, 300, 400, and 600 respectively

 

 First choice is the least

 

hope this helps feel free to ask if you don't understand anything

Why would the highest value be the lowest momentum ? i am kind of confused about that

So the momentum formula is as follows

 

momentum ( m/s) = mass (kg) * velocity (m/s)

 

if we plug the numbers in that's what you get

 

also it's good to know that the greater the mass the greater momentum assuming equal velocity

Also don't give yourself a down point since your question shows you want to learn and isn't one of those "what's 1+1" questions

when i multiply 3000*0.2 I get 600, so wouldnt it be the highest. so the answer would then the lowest which is the one that has the lowest momentum (so  A since it is 100)?

My apologies, I read the question wrong. Yes then the 100 would be the answer.
