11. In a grocery store, you push a 14.5 kg shopping cart. It is initially rolling at a constant speed of 2.0 m/s. You push on it in the direction opposite to its motion exerting a force of 12.0 N. (Ignore friction for
all parts of this problem.)
a. Draw a free body diagram for the cart when you start pushing in the direction opposite to its
motion.
b. Write Newton's second law in component form for the process.
C. Assuming you push the cart exerting constant force for a while, how far will it travel in 3
seconds?

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.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
