m=5000kg d= 4.0cm=0.04m You are looking for k=? hooke's law is f=kx.

How do you get force?

s3a Group TitleBest ResponseYou've already chosen the best response.1
Force caused by gravity is: F = m(g) = mg = (5000kg)(9.8N/kg) (negative means downward) F = 49000 N (negative means downward) F = k(Δy) 49000 = k(4) (Δy is negative because the initial position is at 0 meters and the final position is at 4 metres so Δy = 4  0 = 4 metres. Also notice that Δy being negative means that the truck went downward by 4 meters when the pot hole was hit.) (When people say F = kx, you treat x as the distance that was moved while ignoring the sign but the way I did it makes you systematically think about it.) 49000/(4) = 49000/4 = k = 12250 N/m (This is the spring constant  it means that in order to move the spring by 1 meter from its natural position where it would remain if nothing was forcefully compressing or stretching it, 12250 N of force would be required.)
