Solve with euler method in excel software

The following equation can be used to model the deflection of a sailboat mast subject to a wind force: dy f(z) (L z)? dz2 2E1 = where f(z) = wind force, E = modulus of elasticity, L = mast length, and I = moment of inertia. Note that the force varies with height according to 2007 f(z) = = e-27/30 5 + z Calculate the deflection by euler method in excel saftware if y= 0 and dy/dz = 0 at z=0. Use parameter values of L= 30, E = 1.25 * 108, and I = 0.05 for your computation. (Step size AL=1, L. = 0, L 30 = 30) =
