Homework Help: Projectile Motion -- the landing of a rubber duck...

  1. Nov 16, 2015 #1
    1. The problem statement, all variables and given/known data
    Calculate the magnitude and direction of the velocity of the rubber duck the second it lands?

    2. Relevant equations

    3. The attempt at a solution

    I'm confused, surely if it has landed then it has no magnitude or direction? as the object is now stationary.

    In these types of questions, you should interpret "the second it lands" as meaning "just before contact with the ground". So the duck is still in projectile motion at the time you are asked to find the velocity. The wording of the question was not very good.

    Ah ok, thanks. Yeah it's confusing >.<
