    Car Egg Project
AI Thread Summary
The project requires building a car with an egg attached that can travel specified distances and stop autonomously, without using compressed gases, explosives, or premade parts. Participants are encouraged to explore various energy storage methods, with rubber bands being a potential option for turning the axle. Measuring force and maximum extension of the elastic can help determine the energy storage capacity needed for the car's movement. Springs or weights positioned at a height are also suggested as alternative energy sources. Overall, careful planning and testing of energy storage methods will be crucial for achieving the project goals.

for class we have to make a car with an egged attached to the front (so its protruding). the car has to be able to stop on its own and travel distances of 6m, 8m, 10m, and one even numbered mystery distance between 5m and 10m. compressed gases, explosives, and premade parts may not be used. i have no idea where to even begin :(

Think of several ways of storing energy that are allowed and think about how to implement each. Likely one will stand out as being relatively easy to set up. You will need a fairly good range of adjustment to cover all those target distances.
 
im currently thinking of using rubber bands to turn the axle, but I am not sure if that will be able to go far enough
 
It probably can be done with elastic bands. A quick measurement of the F and maximum x would give you an idea how much energy can be stored in the prospective elastic and you could compare that to the work needed to pull the car. That way you can choose an appropriate size for the elastic(s) before building.

You might try springs or weights at a height.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
