Homework Help: Spring Question

  1. Sep 20, 2006 #1
    A 86.3g ball is dropped from a height of 52.3cm above a spring of negligible mass. The ball compresses the spring to a maximum displacement of 4.9296 cm. The acceleration of gravity is 9.8m/s^2. Calculate the spring force constant k. answer in units of N/m.

    Conservation of energy ofcourse. :)
    Take the reference level as the level at which the spring is compressed to the maximum displacement. Do you think you can go from there?

    i have a similar question, except with different values.

    135 g for mass of ball

    62 cm above spring

    9.8 is same for gravity
