The average power is 10 watts. What's the question ?
kinetic energy is converted into elastic potential energy stored in the brakes.
If I'm not mistaken it should be the digestive system due to the fact that our mouths and stomachs break down food and our intestines absorb any water and nutrients
Work = Force x Distance
Assuming that this work is being done parallel to the displacement that is, but under that assumption:
W = (50)(10)
W = 500 J
Beaker would be most appropriate for measuring the approximate volume of a liquid.
