A golfer lines up for her first putt at a hole that is 10.5 m exactly northwest of her ball's location. She hits the ball 10.5 m and straight, but at the wrong angle, 40° from due north. In order for the golfer to have a "two-putt green," determine (a) the angle of the second putt and (b) the magnitude of the second putt's displacement. (c) Determine why you cannot determine the length of travel of the second putt.
