Homework Help Overview

The discussion revolves around a project to design a car that can travel 10 meters using only a 2kg weight as a launching mechanism. Participants are exploring various constraints, including the prohibition of motors and certain materials, while considering the size limitations of the project.

Discussion Character

  • Exploratory, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • Participants are discussing potential launching mechanisms, including the use of pulleys and ramps. There is a focus on how to effectively utilize the 2kg weight for propulsion while adhering to the project constraints.

Discussion Status

The conversation is ongoing, with various ideas being proposed, such as using a ramp and gate system or pulleys. Some participants are questioning the feasibility of certain methods and are seeking further suggestions to refine their approach.

Contextual Notes

Participants have noted the importance of not exceeding the 10-meter distance and the need for a mechanism that allows for quick acceleration and stopping. There is also a requirement that the launching mechanism must not remain attached to the car after launch.

We have to make a car then make it go 10 meters using only a 2kg weight. no store bought cars, no moters, fuses, electricity, only allowed to use the force of the 2kg(no rubber bands, springs, etc.) We need ideas for a launching mechanism. can only be 1 cubic meter in size. IMPORTANT: must not go past 10 meters(we have a breaking mechanism in mind)
 
Physics news on Phys.org
One thing you may want to consider is rotational inertia. Sounds like you'd want to be able to start and stop quickly. So the wheels should be small and light.
 
Thanx for the advice but what we really need is a way to launch our car. we basiclly have our car made already
 
Can you use a string and pullies attached such that when you drop the mass the car moves then stops at the assembly?
 
we can use string and pulleys but we can't keep the string atached to the car after it is launched. we haven't figured out a good way to use it tho so suggestions would be welcomed
 
Could you create a ramp and a gate? Release the gate and the car accelerates down the ramp. This would work well because you could angle it just right so that it goes about 10m. "Use 2kg" sounds to me like they're saying use gravity and inertia!
 
althought that is a good idea i failed to mention that we need to get the car to go 10 meters as fast as possible
 
stick some kind of spring between the car and the back ?
