A golfer lines up for her first putt at a hole that is 10.5 m exactly north west of her ball's location. She hits the ball 10.5 m and straight, but at the wrong angle, 41 degrees from due north. A. In order for the golfer to have a "two putt green" determine the angle of the second putt. B. Determine the magnitude of the second putt's displacement.
