Assume that a vaulter is able to carry a vaulting pole while running as fast
as Carl Lewis in his world record 100-m dash (around 12 m/s). Also assume
that all of the vaulter's kinetic energy is transformed into gravitational
potential energy. What vaulting height could that person attain?
(Hint: Use the equation 1/2 mv^2? = mgh.)
