1. What net force is required to accelerate a car at a rate of 2 m/s2 if the car has a mass of 3,000 kg?

F =

M =

A=

Net force required to accelerate the car is 6000 N

Explanation:

Here, mass = 3000 kg and acceleration = 2 m/s²

⇒ Force = Mass × Acceleration

              = 3000 × 2 = 6000 N

⇒ F = 6000 N

⇒ M = 3000 kg

⇒ a = 2 m/s²

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.
