1. The problem statement, all variables and given/known data 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? 2. Relevant equations F=-KX F=ma [tex]\Delta X=VoT+.5aT^2[/tex] 3. The attempt at a solution So I did a=F/m to get the acceleration then plugged that into [tex]\Delta[/tex] 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.
