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?
