ron j asked:


lets say a car is traveling from New Youk to Los Angeles.
YOu are assigned to design this car so that it makes it to Los Angeles. YOu are only allowed 10 gallon tank of gas to start and thats the only gas you are allowed to have for the entire trip.

Your car design must be for an electric car that will therefore be able to generate power while it travels from solar energy, using the wind, plus any other innovative ideas you can come up with.

Could this car be designed. HOw many different power sources can you imagine creating as the car travels?

asama asked:


I want to know how the car overtakes a bike even when both are traveling at a same speed.I will put my question in a easier way.

Ex:A bike and car travels at 60mph starting at the same point and time . My question is whether both will reach 60miles after one hour simultaneously?. I know obviously car will reach faster than bike. Whats the reason behind this ??

Kindly answer my question.
