A landscape architect is designing an artificial waterfall in a city park. Water flowing at a speed of 1.70 m/s will exit a horizontal channel at the top of a vertical wall with a height of h = 2.35 m, subsequently falling into a pool as illustrated in the figure. To gain approval from the city council, they need to ensure that the area behind the waterfall is sufficiently wide for a pedestrian walkway. The minimum required width for the walkway is 1.10 m, allowing two pedestrians to walk side by side comfortably. Will there be enough space behind the waterfall for the walkway?  Find the width of the space behing the waterfall and compare to 1.10 m, and answer in your scratch paper with your work. Enter the width you have found below. (20 points)
