What acceleration will result when a 12 n net force is applied to a 3kg object? A 6kg object?

To find the acceleration of an object, you can use the formula:

acceleration = net force / mass

For a 3kg object with a net force of 12N:
acceleration = 12N / 3kg = 4 m/s^2

For a 6kg object with a net force of 12N:
acceleration = 12N / 6kg = 2 m/s^2

Therefore, the acceleration of a 3kg object with a 12N net force is 4 m/s^2, and the acceleration of a 6kg object with a 12N net force is 2 m/s^2.
