Two objects moving with a speed v travel in opposite directions in a straight line. The objects
stick together when they collide, and move with a
speed of v/3 after the collision.
A- what is the ratio of the final kinetic energy of the system to the initial kinetic energy (Kf/Ki=). B-what is the ratio of the mass of the more massive object to the mass of the less massive object (M/m=)

d) the number of neutrons plus the number of protons

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

a is the best answer your welcome
