Acar is parked on a cliff overlooking the ocean on an incline that makes an angle of 24.0 º below the horizontal. the negligent driver leaves the car in neutral, and the emergency brakes are defective. (this car is a stick-) the car rolls from rest down the incline with a constant acceleration of 4.00 m/s2 and travel 50.0 m to the edge of the cliff. the cliff is 30.0 m above the ocean

answer; ///i believe that the correct answer is (carbon); good luck

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.
