Homework Help Overview
The discussion revolves around calculating the displacement of two skiers, one Canadian and one Norwegian, using equations of motion. The original poster expresses confusion about the problem and the relevant equations.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants suggest writing down the equations for displacement for both skiers and discuss the conditions under which the Canadian skier overtakes the Norwegian skier. There are questions about the meaning of variables such as d1 and d2, and the nature of the position-time graphs for each skier.
Discussion Status
Some participants have provided equations for the displacements of both skiers, while others are seeking clarification on the variables and the conditions for overtaking. There is a mix of attempts to guide understanding and expressions of uncertainty regarding the problem.
Contextual Notes
The original poster has not made any attempts to solve the problem, and there is a suggestion that they may need to review the underlying material. The discussion includes references to specific equations of motion but lacks consensus on how to proceed with the problem.

To help you get started:
1. Write down the equation that describes the displacement (distance in this problem) of the Canadian skier and then the Norwegian skier.
2. What does it mean (think in terms of the above equations) for the Canadian skier to overtake the Norwegian skier? What condition must be satisfied?

1. d2-d1?
2. The Canadian skier has a parabola as its position time graph and the norwegian one has a diagonal straight line starting at 1m on the y axis.
Could you explain the solution?

I have no idea what d2 and d1 are.
As for 2, you didn't really answer the question. The Canadian skier overtakes the Norwegian skier when they've gone the same distance.
What equation describes the distance that the Canadian skier has gone in some time t? And what equation describes the distance that the Norwegian skier has gone?

Yes I am not sure about the answer that is why I am asking here.

If you still can't even attempt the problem after what I've told you, you need to go back and actually learn the material.
The displacement of the Canadian skier is given by:
[tex]x = x_{0} + v_{i}t + \frac{1}{2}at^2[/tex].
The displacement of the Norwegian skier is given by:
[tex]x = x_{0} + v_{i}t[/tex].
You do the rest.

Could you please write a solution? I still am not getting the correct answer.
