Homework Help: Bouncing ball?

  1. Feb 20, 2014 #1
    1. The problem statement, all variables and given/known data
    A ball hits the wall.So wall will exert an equal and opposite force the ball
    Why doesn't the ball's forces gets equal so it moves with constant velocity?

    2. Relevant equations

    3. The attempt at a solution
    No attempt needed here.F-F=0 net force.

    Welcome to PF :smile:
    The ball exerts a force on the WALL and the wall exerts a force on the BALL.
    So the forces are not acting on the same object to be cancelled.Newton's third law doesn't state that.
    For every action,there is an equal and opposite reaction.That does not mean the forces act on the same object. :wink:
