SUMMARY
The discussion focuses on the displacement calculations for Canadian and Norwegian skiers, specifically how to determine when the Canadian skier overtakes the Norwegian skier. The displacement equations are provided: for the Canadian skier, the equation is x = x0 + vit + ½at2, while for the Norwegian skier, it is x = x0 + vit. The key condition for the Canadian skier to overtake the Norwegian skier is that both skiers must have traveled the same distance at a given time t.
PREREQUISITES- Understanding of kinematic equations in physics
- Familiarity with displacement and distance concepts
- Basic knowledge of parabolic motion and linear motion
- Ability to solve equations involving time, initial velocity, and acceleration
- Study kinematic equations in detail, focusing on acceleration and displacement
- Learn about the graphical representation of motion, including parabolas and straight lines
- Explore the concept of relative motion and how it applies to overtaking scenarios
- Practice solving problems involving multiple objects in motion with different acceleration rates
Students studying physics, particularly those focusing on kinematics, as well as educators looking for examples of displacement calculations in real-world scenarios.

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:
x = x_{0} + v_{i}t + \frac{1}{2}at^2.
The displacement of the Norwegian skier is given by:
x = x_{0} + v_{i}t.
You do the rest.

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