Mass attached to spring on frictionless table

[cflemer]

Homework Statement

An ideal spring of an un-stretched length 0.10 m is placed horizontally on a frictionless table. One end of the spring is fixed and the other end is attached to block of mass M = 10 kg. The 10 kg block is also attached to a massless string that passes over a small frictionless pulley. A block of mass m = 2 kg hangs from the other end of the string. When this spring-and-blocks system is in equilibrium, the length of the spring is .20 m.

Calculate tension in the string.

Calculate the force constant of the spring.

(there is a diagram, but it is complicated and I don't know how i would get it on here)

Hi cflemer !Welcome to PF!

(there's no need for a diagram … your description is fine )

Show us what you've tried, and where you're stuck, and then we'll know how to help.
