The initial velocity and acceleration of four moving objects at a given instant in time are given in the following table. Determine the final speed of each of the objects, assuming that the time elapsed since t = 0 s is 2.0 s.

initial velocity accerlation
+13m/s -3.3m/s^2
+13m/s -3.5m/s^2
-12m/s +3.1m/s^2
-13m/s -3.0m/s^2

    1. Vf = Vi + at.

    Vf = 13 + (-3.3)2,
    Vf = 13 - 6.6 = 6.4m/s.

    The remaining problems are the same.
