Homework Help: Object being dropped at different height

  1. Sep 20, 2012 #1
    When an object is being dropped at different height assuming no friction will it have the same
    speed at the same time?

    Lets say an object was dropped at 10m and 5m

    at 3seconds would the speed be the same?


    using the formula i would assume they would have the same velocity at the same time even in different heights.
    is this correct?

    i think you are correct because there is no friction so yes. if there was friction no.

    Yes, because the initial velocity of both would be 0 m/s and gravity would at equally on them both at -9.81 m/s^2 so at the same time they would have the same speed.
