Calculating force nessary to compress spring

  1. Sep 6, 2009 #1
    The data for a ball and spring sensor is given below:
    mass of ball = 0.12kg
    spring constant = 30Nm-1
    distance to be compressed = 3.6cm

    Calculate the force nessary to compress spring by 3.6cm.
    The deceleration which the force in (the 1st question) would cause in a mass of 0.12kg.

    i seem to find this question quite tricky, mainly becasue im not sure of what equation to use!
    please me on this one!!

    What does Hooke's law tell you about springs and Newton's 2nd law tell you about acceleration?
