Homework Help Overview

The discussion revolves around a momentum problem involving calculations of momentum components in the y-direction based on given angles and distances. The original poster describes a scenario where they must calculate momentum without focusing on the x-direction, using the formula p=mv, with a mass of 1 unit and unspecified units for distance.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the calculation of y-components of momentum using trigonometric functions based on given angles. The original poster questions the distinction between distance and the y-component, while others seek clarification on the exact question being addressed.

Discussion Status

The discussion is ongoing, with participants exploring different scenarios and calculations. Some have provided specific values and methods for calculating y-components, while others have requested clarification on the original question. There is a mix of understanding and confusion among participants.

Contextual Notes

Participants note the lack of specific units for the calculations and the requirement to focus solely on the y-direction. There is mention of different angles and distances in the scenarios presented, which may affect the calculations being discussed.

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 don't know 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.
 
don't worry, my prof explained and it now makes sense, thanks tho
