The weight (mg) of the object on the moon would be 1/6th of its weight on Earth. Therefore, mg on the moon = (15 kg) x (1/6) x (9.8 m/s^2) = 24.5 N
To accelerate the object at 8.0 m/s^2, we need to apply a net force F = ma, where m = 15 kg and a = 8.0 m/s^2. Therefore, F = (15 kg) x (8.0 m/s^2) = 120 N
So the net force required to accelerate the object at 8.0 m/s^2 on the moon is 120 N.

Therefore, the correct answer is D.
