1. The problem statement, alml variables and given/known data A block of mass 2 kg is suspended from a fixed support by a spring of strength 2000 N m^-1. The block is subject to the vertical driving force 36 cos pt N. Given that the spring will yield if its extension exceeds 4 cm, find the range of frequencies that can safely be applied. Take g = 10 m s-2 2. Relevant equations m*x'' + b*x'+kx= F(t) x''+2*K*x' + [tex]\Omega[/tex]2=F0cos(pt) 3. The attempt at a solution 2*x''+ b*x'+ 2000*x=36*cos(pt) N what is the extension, and how would I find the range of frequencies.
