In figure 4, an object of mass 10 000 g is released at point A, slides to the bottom of the 30° incline, then collides with a horizontal massless spring, compressing it a maximum distance of 75 cm. The spring constant is 560 N/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless while the incline has some fiction. What is the speed of the object at the bottom of the incline?

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.

technology is the application of the knowledge gained by science.
