Free fall with + and - Vinitial

  1. Feb 26, 2016 #1
    Two objects thrown from a cliff. One with + vinitial (upward) One with - vinitial (downward). Does the one with + vinitial not reach a greater height and thus have a larger vf upon hitting the ground since it falls farther and therefore is subject to gravity longer?

    Yes. perhaps your argument is correct but check their initial velocities (from which they start falling under gravity) and then calculate Vf... then you may be wrong!

    If you throw an object upward from the top of the cliff, it will normally come back down again. When it does so and is level with the top of the cliff, what is its velocity then?
