Converting the energy of one food calorie into mechanical energy, starting from rest, to what speed could you accelerate a 133-lbs person?
1 calorie= 4.184J
1 lbs= 0.453592kg
The Attempt at a Solution
here what I did, I converted the lbs to kg which was 60.33kg. I was under the impression to use kinetic energy.
sqrt 4.184J/30.165kg= 0.372m/s
This is how I solved my problem, but I got 1 out of 10. Can someone explain to me what I did wrong?
