To find the acceleration of the object, we can use the formula:

a = (Vf - Vi) / t

where:

a is the acceleration,Vf is the final velocity,Vi is the initial velocity,t is the time.

Given that the initial velocity (Vi) is 0 m/s (assumed that the object starts from rest), the final velocity can be calculated using the formula:

Vf = Vi + at

Vf = 0 m/s + 5 m/s^2 * 5 s
Vf = 25 m/s

Now we can calculate the acceleration using the first formula:

a = (25 m/s - 0 m/s) / 5 s
a = 5 m/s^2

Therefore, the acceleration of the object is 5 m/s^2.
