Homework Help Overview

The discussion revolves around a physics problem involving motion in a moving train, specifically analyzing the horizontal displacement of a person who jumps vertically while the train is in motion. The train travels at a speed of 430 km/h, and the jumper's vertical speed is 2 m/s.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants explore the implications of jumping in a moving train and question the forces acting on the jumper during the jump. There is a focus on understanding horizontal displacement and the absence of horizontal forces.

Discussion Status

Some participants have provided guidance on the need to clarify assumptions and fill out the homework template. There is an ongoing exploration of the relationship between vertical and horizontal motion, with no clear consensus yet on the outcome of the problem.

Contextual Notes

Participants note the requirement to follow a specific homework template and express the need for showing work to identify where they are encountering difficulties. There is a mention of the direction of displacement being defined in relation to the train's movement.

I'm taking a trip aboard the Shanghai Transrapid Train. The train maintains its maximum commercial speed of 430km/h along a straight.
I position myself at the centre of my carriage and jump straight up at 2ms-1.

How many horizontal meters am I displaced along the aisle before landing?

Displacement towards the front of the train is negative and towards the back of the train is positive

You need to fill up the three part template and show your working.
It is mandatory while posting here in the homework help forum.
 
You too traveling as fast as the train, horizontally.
Is there any force acting on you horizontally?

If there is no horizontal force acting on you then where do you land?

Lani, you need to start over and fill out the homework template and show what you have attempted to solve the problem yourself so that we know where you are getting stuck. :smile:
