A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.72 m/s will leave the end of a horizontal channel at the top of a vertical wall 2.80 m high, and from there the water falls into a pool. Will the space behind the waterfall be wide enough for a pedestrian walkway?
