please explain in stepwise​

Answer 1

Answer:

Explanation:

Can you tell from which book u got the question?

Mass is given to mislead us .

Using common sense we can find change in speed as 0 since no acceleration

But for doing velocity we must follow vector subtraction since it has direction also represented by + and - here
