Homework Help: A conceptual Question

  1. Sep 29, 2008 #1
    1. The problem statement, all variables and given/known data

    A Ball is thrown straight up. Taking the drag force of air into account, does it take longer for the ball to travel to the top of its motion or for it to fall back down again?

    2. Relevant equations

    3. The attempt at a solution

    Do not know where to start with the question.

    Start with the forces that will act on the ball; these are "gravity" and "drag" force (likely to be quadratic for your scenario). Use Newton's second law and derive appropriate equations; of course, you probably could find these somewhere.

    Does this help at all?

    Hint: Compare the acceleration of the ball going up versus going down.
