[6.1] Question: Rank the magnitude of the change in momentum of a ball from largest to smallest for the following situations: a. The ball is moving with constant velocity, hits a wall, and stops moving. b. The ball is moving with constant velocity, hits a wall and bounces back with its original speed. c. The ball is moving with constant velocity, misses the wall and continues onward, changing neither speed nor direction

b would be the answer

the answer is a. at the equator

b.transmitters send radio waves, and receivers capture radio waves.

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.
