You are trying to access the puck using the classname (Puck) but that's only possible if the method is static. For non static methods you have to use the reference name (puck in this case).

Just change Puck.setSpeed(7); to puck.setSpeed(7); (no capital letter).

This is partially true. You'll also need to do a cast to the correct type. Change this: 
    Actor puck = getOneIntersectingObject(Puck.class);
    if (puck != null) {
        Puck.setSpeed(7);
    }
to this: 
    Puck puck = (Puck) getOneIntersectingObject(Puck.class);
    if (puck != null) {
        puck.setSpeed(7);
    }
