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.
