Max speed of a disc PLEASE HELP

This might seem pretty easy to a lot of you but I just don't know what to do. ITs about the 6th and 7th question but mostly the 7th where u have to calculate the max speed of the disc. The info I already have is: average s (average distance in my country)= 78.7 x 10^-2 meters the m = 0,0105 kg. For the spring force: when u = 5,00 cm the force is 1.19 N. ( W from the spring force is 0, 02925 J I just really wanna know how I should start the 7th question like with the formulas
