This is the ball rolling on the table for 3 sec
and rolls 10 cm/sec and then rolling back
-5cm/sec.. Remember I stated that this can be
done by common sense or with the equationswell,
here is the equation way of doing it.

This is the information that was given in the
problem.
This is what you are asked to solve for.
This is what you are missing.
Start by calculating velocity of given information
Now substitute into average velocity equation and
solve for Vf.
Once you solve for Vf then plug into acceleration
equation. Final answer should be.0.02 m/s2
Note I did not conduct shortcuts on algebra so
all steps are in there including substitutions.

This is the continuation from last question. It
now wants to know what is the velocity of the
object after 5 sec. Since you now know the
acceleration and Vi and time is 5 sec.all you
need to do is plug into equation again and solve
for Vf.
