Newton 2nd Law calculations

According to Newtons second Law, if you push with 2N on an object with a mass of 5kg how much should it accelerate? ____m/s^2

Newton's second law of motion says that an object's acceleration is greater when the _________ on the object is greater.

Acceleration is less when the ________ of the object is greater.
