A landscape architect is planning an artificial waterfall in a city park. Water flowing at 0.747 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.55 m high and falls into a pool (see figure). | | (a) How far from the wall will the water land? m Will the space behind the waterfall be wide enough for a pedestrian walkway? (Assume the water must land 2 m from the wall to provide adequate space for a person to walk beneath the waterfall.) Yes No (b) To sell her plan to the city council, the architect wants to build a model to standard scale, one-twelfth actual size. How fast should the water flow in the channel in the model? m/s
