Question

If a 71.0 kg , 1.70 m -tall human could jump to the same height compared with his length as the flea jumps compared with its length, how high could he jump, and what takeoff speed would he need?

Answer 1

height=1.7 x ?? my guess is 40x
then velocity is equal ...
v^2=2*h*9.8
solve for takeoff velocity v
