Help with building a battery transporter for physics

[michellex]

we have to build vehicle that can transport a d cell battery 7 meters as fast as possible using the potential energy of no more than 2 kilograms falling from 80cm.

we want to use this design:

but we're not sure how to build it exactly so if you can, please help us get started!

If your school has a machine shop, use that. It should have a supply of wood that you can use to construct the frame. If you can't make metal wheels, you might have to improvise with wooden ones.

I would recommend starting by calculating the potential energy of a 2 kilogram object falling from 80cm. This will give you an idea of the amount of energy you have to work with for your battery transporter. From there, you can begin designing and building your transporter using the design shown in the links provided. It may also be helpful to consider factors such as friction, aerodynamics, and the weight of the battery itself in order to optimize the speed and efficiency of your transporter. Additionally, testing and making adjustments as needed will be crucial in achieving the desired outcome. Good luck with your project!
