Answer: = 5 m/s
Explanation: For collisions, use linear momentum, whose formula is: P = m.v and knowing the law of conservation states that momentum of a closed system is constant in time, i.e. initial momentum equals final momentum:
Suppose the referential for velocity is positive to the right:
The negative sign, in this case, indicates cart A is going to the left.
The magnitude of velocity of cart A is 5 m/s
To help, I wrote an example of the poem prompt you gave(Images -- should read from left to right) In the example, I used irony to show contrast and contradictory from the speaker's tone and veiw at the begining of the poem compared to at the end of the poem. I tried to incorporate a story into the poem because I figured out a good way to tell a--what is a rather mediocre--story with the given prompt. I incorporated this story into the poem simply by sticking to an ABB rhyme scheme throughout the entire thing. There are of course an endless number of ways one could write a poem, for poetry is often seen as more of a creative, expressive form of writing rather than a technical one. If you have an idea and you can manage to formulate it in stanzas, there's not much that can go wrong.
