Mass attached to spring on frictionless table

  1. Nov 17, 2008 #1
    1. The problem statement, all variables and given/known data
    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)


    2. Relevant equations
    F=ma


    3. The attempt at a solution

    Hi cflemer !Welcome to PF! :smile:

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

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