To calculate the force necessary to accelerate the object horizontally at (3 , m/s^2), we can use Newton's second law of motion, which states that force ((F)) equals mass ((m)) multiplied by acceleration ((a)).

[F = m \times a]

Given that the mass ((m)) of the object is (12 , kg) and the acceleration ((a)) is (3 , m/s^2), we can substitute these values into the formula to find the force ((F)) required:

[F = 12 , kg \times 3 , m/s^2]
