Homework Help: Conservation of Energy: Spring onstant

  1. Dec 7, 2012 #1
    1. The problem statement, all variables and given/known data
    if a basketball of mass=5kg is dropped from a height of 3 cm hits the ground and it compresses 0.015m then what is the spring constant

    Please demonstrate effort and show one's work.

    What is the potential energy of the ball with respect to the impact point?

    What is the mechanical energy of a compressed spring in relation to spring constant and deflection?

    Answer both questions and solve the problem.

    use the conservation of energy.


    all the the gravitational energy turns into elastic potential energy.

    so Eg1 = Es2

    mgh = (1/2)kx^2
