For a science project I have been given two solar cells, one of 1 V and 0,4 A and another of 2V and 0,55 A. We are two use these solar cells (and other material) to build a toy car.
We also need to calculate how fast this car will move and I don't have a clue where to start.Is there anyone out there that can help me how to think? What factors will decide how fast the car will move?
Thanks from

Power = current x voltage.
Power is also = energy dissapated / time
Equate these two formulas
You have current and voltage. You need to work out energy dissapated. I beleive this would depend on your efficiency of your solar cell. How much incident light it takes in and turns into useful power output. I think you need more information, maybe.
Just a quick guess, might get you started anyway.
