A daredevil of mass m jumps from a bridge attached to a light bungee cord of length L and stiffness k and falls under the influence of gravity g. Let u(t) be the amount the cord is stretched at time t. According to Hooke's Law and Newton's Second Law mü= mg – ku/L. (1) = (a) What are the units of the four parameters m, L, k and g? (b) Use dimensional analysis to find a general formula for the total distance H fallen by the bungee jumper in terms of the parameters.
