Runge Kutta Method. Use mat lab for program with Runge Kutta. The following equation can be used to model the deflection of a sailboat mast subject to wind force. d^2y/dz^2=f/2EL (l-z)^2 where f= force of the wind, E= module elasticity, L= mast lengh, I= inertia moment. Calcule the deflection if y=0 and dy/dz=0 at z=0. Use parameter value of f=50 , L= 30, E= 1.2 x10^8 and I=.05 for the computation.
