A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

Kenny is climbing the stairs of his apartment building for exercise. Kenny weighs 83 kg and the height of a single step on the staircase is 11 inches. He climbs a flight of stairs in 4.0 seconds. a.) calculate the rate at which the stairs can be climbed considering the given information (stairs per second). b.) How long can kenny sustain this pace (so like, continuously climbing the stairs and not leaping up a bunch of stairs at one instant)? c.) Why does Kenny descend stairs at a faster rate for a nearly unlimited time although very similar forces are exerted descending as they are ascending?(This points to a fundamentally different process for descending versus climbing stairs.)
