Explanation:
a) Two balls are at a distance of L/2 from the axis of rotation and one block at the center. ( center of rod).
therefore,
b) two balls at a distance L/4 at the from the axis and 1 ball at a distance 3L/4 from the from the axis.

Positive acceleration is a parabola pointing upwards.
Negative acceleration is a parabola pointing downwards.
I am not sure what you mean by the balanced forces. But I guess it means no acceleration which is a straight line. It can be a horizontal line or an inclined line.
Hi there!
We can use the following equation to derive acceleration:
vf = vi + at, where:
vi = 0 m/s (starts from rest)
a = acceleration
time = time (sec)
Rewrite:
vf = at
Solve for acceleration:
vf/t = a
30/6 = 5 m/s²
