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 thats 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 Im kinda lost... Any help is appreciated!!
