A block of wood is compressed 2.0 nm when inward forces of magnitude 120N are applied to it on two opposite sides. (a) Assuming Hooke's law holds, what is the effective spring constant of the block? (b) Assuming Hooke's las still holds, how much is the same block compressed by inwrard forces of magnitude 480N? (c) How much work is done by the applied forces during the compression of part (b)?

k = 120/2*10^-6 N/m

b) four time as far

W = (1/2) k x^2 = (1/2)(120/2*10^-6)(8*10^-6)^2
