Abook that has a mass of 0.5 grams is pushed across a table with a force of 20 newtons what is the acceleration of the book? a.10 m/s^2
b. 0.025 m/s^2
c.40 m/s^2
d.40 m/s

Explanation:

To solve this equation ,we need to apply Newton's second law. Which defines

Force = Mass* Acceleration

Mass  = 0.5 g = 0.5*10^-3 Kg

Force  = 20 N

Acceleration = Force / Mass

Acceleration  = 20 N /0.5*10^-3 Kg

Acceleration  = 40000 m/s^2

I believe you meant a mass of 0.5 Kg

In that case, the acceleration would be

Acceleration  = 40 m/s^2

Option C

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

i think the answer is a, hope this : )
