    I have no idea how to do these questions. My teacher did not explain anything.

    Anyways my question is:

    A watercraft with an initial velocity of 6.4 m/s [East] undergoes an average acceleration of 2.0 m/s^2 [South] for 2.5 s. What is the final velocity of the watercraft?

    This are going in different directions. How do i do these types of questions? Please help me.
