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?

1. Andrew and Kevin decide to try out the physics ideas that they are learning and take their baseball pitching machine and a baseball to a 96 feet tall local building. Based on what they have learned the height, s(t), of a baseball, thrown straight up with an initial speed of 80 feet per second from a rooftop 96 feet high is s(t)=-16t^2+80t+96 where t is the elapsed time that the baseball is in the air. The baseball that is pitched miss the rooftop on their way down and eventually strike the ground. a) What is the average velocity of a baseball from t=0 to t=2 seconds? b) What is the velocity of the baseball 2 seconds after it is thrown? c) After how many seconds will the velocity of the baseball reach zero? d) What is the velocity of the baseball t seconds after it is thrown? e) What is the velocity of the baseball as it passes the roof top on the way down?
3) A red truck moving 100 km/ h overtakes a 1.5 km long train moving in the same direction on a track parallel to the road. If the speed of the train is 80.0 km/h, how long in seconds does it take the car to pass it, and how far (meter) will the car have travelled in this time
A car is traveling at 50 mi/hmi/h down a highway. What magnitude of acceleration does it need to have to come to a complete stop in a distance of 200 ftft? Express your answer in miles per hour squared. What magnitude of acceleration does it need to stop in 200 ftft if it is traveling at 100 mi/hmi/h? Express your answer in miles per hour squared.
2 Two trains, one travelling at 72 km/h and the other one at 144 km/h, are headed toward one another along a straight level track. When they are 950 m apart, each engineer sees the other’s train and applies breaks. If the breaks decelerate each train at the rate of 1m/s2, is there a collision?
