# Homework Help: Simple momentum question

1. Mar 9, 2007

### oridniv

So, we were given a scenario and were asked to not calculate the momentum components in the x- directions. We were asked to use the simple formula of momentum(p) p=mv. Velocity was the root of the distance between the collisions and the mass was 1 unit. No specific units are to be used in these calculations. The question asks us to calculate momentum in the y-direction after being given specific angles. What's the difference between the distance and the y- component again?

It'll be easier for someone to answer if you state the exact question you are trying to solve, along with the work you have done on it (i.e. what you have calculated)

1st scenario:
d=9.4cm
v= square root d= 3.1
I dunno how to calculate the y-components of momentum considering on an x-y plane, d is 34 degrees north of west. What I calculated was 9.4sin34 to get the y components but I can't shake the feeling that I might be wrong

2nd scenario, same as first but different numbers
d=14.7
v=3.83
d is 94 degrees east of north
y-component=14sin93

Could you state the whole question as given. It is quite confusing to me now.
