A block of mass m = 1 kg is kept pressed...

A block of mass m = 1 kg is kept pressed against a spring on a rough horizontal surface. The spring is compressed by 10 cm from its natural length and to keep the block at rest in this position a horizontal force (F) towards left is applied. It was found that the block can be kept at rest if `8 Nle F le 18 N`. Find the spring constant (k) and the coefficient of friction `(mu)` between the block and the horizontal surface.
