A ball is tossed at 10m/s off the top of a 100m tall building. Find its velocity halfway down the building and at the ground.

  • Science -

    which direction was it tossed? upward, downward, horizontally?

    -50=0+vi*t -1/2 g t^2
    solve for time, t.
    then knowing time, solve for velocity.

  • Science -

    it doesn't say in which direction it was tossed, but thank you very much for your help.
