a 2 100 kg car drives east towards a 55 kg shopping cart that has the velocity of .50 m/s west. The two objects collide, giving the car a final velocity of 6.31m/s east and the shopping cart a velocity of 13.5 m/s east. What was the initial velocity of the car?

hypothesising or postulating

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.

the components of a vector are the parts of the vectors that are to each other.
