# Spring scale Problem

## Homework Statement

You use a spring scale to pull a 1.5 kg object on a horizontal frictionless surface with a constant horizontal force of 1.3 N (according to the scale reading). You use a stopwatch to time how long it takes the object, starting from rest, to cover a distance of 2.7 m. What is the reading of the stopwatch?

## Homework Equations

F=-KX
F=ma
$$\Delta X=VoT+.5aT^2$$

## The Attempt at a Solution

So I did a=F/m to get the acceleration then plugged that into $$\Delta$$ X=VoT+.5aT^2 and Vo is equal to 0. After i plugged it all in I got 2.49, is that right? For some reason it seems wrong.
