+1995 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
+773 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....................
+1005 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
+1995 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.
+1005 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
+1995 Why would the highest value be the lowest momentum ? i am kind of confused about that
+1005 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
+1005 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
+1995 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)?
+1005 My apologies, I read the question wrong. Yes then the 100 would be the answer.
