Bill and his daughter Susan are both standing on identical skateboards (with really good frictionless ball bearings), initially at rest. Bill has mass of 55 kg and Susan has 20 kg. Bill pushes a 15 N force horizontally on Susan’s back for 3.0 seconds, causing Susan to start moving away from Bill. Just after Bill stops pushing, what is Bill’s speed moving backwards?
