Question

In 0.414 s, a 8.86-kg block is pulled through a distance of 4.36 m on a frictionless horizontal surface, starting from rest. The block has a constant acceleration and is pulled by means of a horizontal spring that is attached to the block. The spring constant of the spring is 471 N/m. By how much does the spring stretch

    Answer: x = 0.957 m

    Explanation:

    F = ma

    d = ½at²

    a = 2d/t²

    F = m2d/t²

    F = kx

    kx = m2d/t²

    x = 2md/kt²

    x = 2(8.86)(4.36) / (471(0.414²))

    x = 0.957036…
