Question
An $83-\mathrm{kg}$ man eats a banana of energy content $1.00 \times 10^{2} \mathrm{kcal} .$ If all of the energy from the banana is converted into kinetic energy of the man, how fast is he moving, assuming he starts from rest?
Step 1
We know that 1 kilocalorie is equal to 4184 joules. So, the energy from the banana in joules is $1.00 \times 10^{2} \mathrm{kcal} \times 4184 \mathrm{J/kcal} = 4.184 \times 10^{5} \mathrm{J}$. Show more…

An 83 kg man eats a banana of energy content $418 \mathrm{kJ}(100 \mathrm{kcal}) .$ If all of the energy from the banana is converted into kinetic energy of the man, how fast is he moving, assuming he starts from rest?
How fast would an $80 \mathrm{kg}$ man need to run in order to have the same kinetic energy as an 8.0 g bullet fired at $400 \mathrm{m} / \mathrm{s} ?$
