It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia
• Newton's second law, the law of acceleration
• Newton's third law, the law of action reaction 
• The law of universal gravitation

A book rests on a table.  The force of gravity pulls down on the book with a force of 20 newtons. What prevents the books from accelerating downward at 9.8 m/sec²    

• The table presses back up on the book with an equal and opposite force of 20 newtons.
• The table presses back up on the book with a force greater than 20 newtons.
• The table and the book together are accelerating downwards at  9.8 m/sec²
• The inertia of the book holds it up
