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?
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.
