In elastic collisions, total kinetic energy and momentum are both conserved. on a frictionless track, cart 1 is moving with a constant, rightward(+) velocity of 1.0m/s. cart 2 is also moving rightward with constant velocity of 5.0m/s. after a while, cart 2 collides cart 1 from behind.(it is an elactic collision.)if the final velocity of cart 2 becomes 3.0m/s, what is the final velocity of cart 1? (show all your work.)

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
