Question: A flea is able to jump straight up about 0.55 m. It has been said that if a flea were as big as a human, it would be able to jump over a 100-story building! When an animal jumps, it converts work done in contracting muscles into gravitational potential energy (with some steps in between). The maximum force exerted by a muscle is proportional to its cross-sectional area, and the work done by the muscle is this force times the length of contraction. If we magnified a flea by a factor of 950, the cross section of its muscle would increase by 9502 and the length of contraction would increase by 950.

Part A: How high would this "super flea" be able to jump?

Answer in m.

I want help to find how high would this "super flea" be able to jump and don't forget that the mass of the "super flea" increases as well.)
