An object with a mass of 2.0 kg accelerates at 2.0 m/s^2 when an unknown force is applied to it. What is the amount of the force? GIVEN:

REQUIRED:

EQUATION:

SOLUTION:

ANSWER:

ANSWER: 4.0 N

EXPLANATION

The formula for Newton's second law is

where:

Given:

mass (m) = 2.0 kg

acceleration (a) = m/

Required:

F = ?

Equation:

F = ma

Solution:

F = 2.0 x 2.0

F = 4.0 N

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.
