Did I do this right??
How much chemical energy would be consumed to travel 100km?
* Assuming 100% efficency *
Mass of car = 1953 kg
velocity = 22.2m/s
Here is what I did
E = 1/2 m v^2
E = 1/2 * 1953 * 22.2^2
E = 481258.26 J
Now I plugged the Energy I got into this formula
W = F * D
481258.26 = f * 100,000
Divide both sides by 100,000
F = 4.8 N
Ok so that's the work that I have done. I don't think I was supposed to find the force. What is chemical energy. I thought I did it wrong becasue I thought I was supposed to use E = 1/2mv^2 and add the answer to the W =Fd answer.
So I am kinda lost... Any help is appreciated!
