I would like to thoroughly understand each steo to solve this.
In 0.750s, a 7.0kg block is pulled through a distance of 4.0m on a frictionless horizontal surface from rest. the block has a constant acceleration and is pulled by means of a horizontal spring attached to the block. The spring constant is 415N/m. By how much does the spring stretch?

  • physics -

    solve for acceleration
    d=1/2 a t^2 solve for a, then
    f=ma solve for f.
    Then, knowing F
    f=kx

    to solve for a
