If each elephant has a mass of 5000 kg, what is the acceleration of the elephants? (numeric Answers only in m/s^2)

Since Force = mass x acceleration
If the force = 0, then
The acceleration = 0
From the given figure
Since the elephants moved in the opposite directions with the same force, then
The net force = 0
Then the acceleration also = 0
The acceleration of the elephants is 0 m/s^2
