The data in the following table represent the initial and final velocities for a boat traveling along the x axis. The elapsed time for each of the four pairs of velocities in the table is 2.0 s. Determine the acceleration (magnitude and direction) for each of the four pairs.
a. Initial V: +2.0 m/s Final V: +5.0 m/s
b. IV: +5.0 m/s FV: +2.0 m/s
c. IV: -6.0 m/s FV: -3.0 m/s
d. IV: +4.0 m/s -4.0 m/s

@crazyjay100 could you help with this one?

average acceleration = (final velocity - initial velocity)/time elapsed

just take care with the signs when working out the difference between final and initial velocities
