Michael asks…Is this right for the answer? 11 physics?A 200g bag of potato chips contains 4.8 MJ of energy. How long would it take you working at your maximum body power to consume this energy.
Are you just supposed to rearrange the formula Power = Energy / time and solve for time?
My power is 342 W. I divided 4.8 MJ (4 800 000 J?) by my power and got 14035 seconds?
Does this sound reasonable?Nancy answers:Perfect.
4.8MJ * 1000000j/MJ * 1 sec/342 j = 14035 seconds
* 1 min/60 sec = 234
