It's a negative value because the negative sign on the spring's force means the force exerted opposes the spring's displacement
We assume

(acceleration is constant. We apply the equation

where s is the distance to stop

. We find the acceleration from this equation

We know the acceleration, thus we find the distance necesssary to stop when initial speed is

Answer:
T= 4.24sec
Explanation:
We are going to use the formula below to calculate.

Where T is period
L is length of rod
g is acceleration due to gravity =
From the problem, the rod is pivoted at 1/4L which means that three quarter of the rod was used for the oscillation. lets call this

= 4.4625m
thus
T= 4.24sec
