Software is abstract and therefore seems as if it should be infinitely malleable. And yet, for all its ethereal flexibility, it can be stubbornly, maddeneningly intractable, and it is constantly surprising us with his rigidity. (S. Rosenberg)

[ Spring | Le_Sphinx ]
Here starts the Challenge:




Given the following system : the plate of weight M = 1.5 kg is attached to the spring (of constant k), the weight m = 750 g is put on the plate without friction. The system is pressed, and the spring is compressed to a certain length b from its equilibrium position.

What is the maximum value of b, for which m will not leave the plate?

The following data are given :
g = 9.8 N.kg-1
k = 10 N.m-1

b_max = ? m (please give the exact value)

Example: 4.158
