Homework Help: Physics for 8th grade

  1. Dec 18, 2014 #1
    I know the question is simple... but I don't get it.

    A metal ball is thrown from a tall building V0= 0. When will it reach V=25 m/s?

    This is my first question, I seem to like physics yet I don't understand anything... accept electricity, but the rest, I don't. I hope I don't annoy anoyone but I really need help because I want to be good at this subject. Thank you in advance!

    Welcome to the PF.

    When posting schoolwork questions, we ask you to use the Homework Help Template that you are provided when you start a new thread here. You need to fill out the sections of the Template, including the Relevant Equations, and show your Attempt at a solution.

    What equations do you think apply to this question? You need an equation that relates the velocity to the acceleration of the ball.

    And what provides the acceleration force to this ball?
