Physics

At a certain instant an object is moving to the right with speed 1.0 m/s and has a constant acceleration to the left of 1.0 m/s^2.At what later time will the object momentarily be at rest? How do you do this?

  1. every second the velocity decreases by 1.0 m/s.

    Looks like it will take 1.0 seconds to stop.

    time = speed/acceleration

    (m/s) / (m/s^2) = s
