Answer:
Sesmic? Maybe? I don't know your question.
If the student has mass 75 kg, and if the stairs are 3 m high, then
<span>work = mgh = 75kg * 9.8m/s² * 3m = 2200 J </span>
<span>so I'd say "one one-hundredth." </span>
<span>Except that I think 5000 cal ≈ 20.95 kJ (not J), and that would change my answer to </span>
<span>"ten times or so".
