In an open space, Arianna throws a tennis ball at an angle of 26∘ to the horizontal with an initial velocity of 78 feet per second. If the tennis ball is released at a height of 4 feet, the parametric equation would be x(t)=(78cos26∘)t, y(t)=−16t2+(78sin26∘)t+4. After how many seconds does the tennis ball reach its maximum height? (Round your answer to the nearest tenth if necessary.)

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?
