If you push a 900n refrigerator with the same force as you lift a 40n dumbbell, the dumbbell will move faster. according to chapter 12, which of newton’s laws is this an example of? explain how you know.

This is an example of the Second Newton´s Law of Motion.

He formulated three laws. The Second Law of Motion establishes the relation between force, acceleration and therefore velocity.

It states that "The force acting on an object is equal to the mass of that object times its acceleration." This is written in mathematical form as F = ma, where F is force, m is mass, and a is acceleration.

The bold letters indicate that force and acceleration are vector quantities.

On the other hand, the First Law of Motion states that "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force".

Finally, the Third Law of Motion states that "For every action, there is an equal and opposite reaction".

the answer:

in the first part of the story running is all that matters to squeaky. running gives her confidence and defines who she is. at the beginning of the story she says that other kids call her mercury because she runs very fast. in the text she refers to herself as "miss quicksilver".

the line that provides the best evidence that squeaky has self-confidence is

" and i continue with my breathing exercise, strolling down broadway toward the ice cream man on 145th with not a care in the world cause i am miss quicksilver herself".

isn't this axel talking to his uncle?
