Mary has a mass of 40 kg and sprints at 1 m/s.Roberto has twice the mass his sister Mary has (see above) but runs at the same velocity as Mary. Will his kinetic energy be twice as much? Show your work.

Answer: Kinetic energy is entirely dependent on mass. Since Roberto has twice the mass of Mary, his kinetic energy will be twice as much. Hope this helps! :)
