2. Wind blowing past a flag causes it to "flutter in the breeze." The frequency of this fluttering, f, is assumed to be a function of the wind velocity, V , the air density, rho, the acceleration of gravity, g, the length of the flag, l, and the "area density" (mass per unit area) of the flag, WA. Find the appropriate Pi groups to characterize fluid mechanics phenomena that causes the fluttering.

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
