if initial time is zero, and we drop subscript on final variables.
A little red wagon is rolling in the positive direction with an initial speed of 5.0 m/s. A child grabs the handle and pulls, giving it a constant acceleration of 1.1 m/s2 opposite its initial motion. Let the time the child begins to pull be t=0, and take the position of the wagon at that time to be x=0.
How fast will the wagon be going after 1.0 s of pulling?
Where will the wagon be then?
At what time will the wagon come to a stop (for an instant)?
Yeah – consistency!
