Strugglin with this one

  1. Jan 26, 2007 #1
    This problem is telling me that an arrow is shot from a bow with a speed of 20.5 m/s. THen asking if the average force exerted on the arrow were doubled with everything else staying the same, with what speed would the arrow leave the bow? I am just confused I thought it would stay the same? Can anyone help?
