The energy equation would work great in this scenario:
E=K+U. Since all of our energy comes from gravitational potential energy, and we are interested in finding the kinetic energy, all our mechanical energy must be in kinetic form, therefore:
We can use energy to find max height.
For energy, set the equation E=K+U as 437.7=(mass adult+mass senior)gh:
