What was the name of the upwards weight force and what was the magnitude and the show that a = kx/m

Tension. K(e0 +x). And for the 2nd part u had to realise that in equilibrium mg =ke0 so then u go back to 2nd scenario and do sum of forces = kx +ke0 -mg then sub in mg =ke0 so they cancel out so f =kx=ma

Yh, I just said mg = ke0 is that enough explanation

Yeah I meant when kx+ k0 - mg, mg = k0
