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?

A river has a steady speed of 0.440 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. (a) If the student can swim at a speed of 1.15 m/s in still water, how long does the trip take? S (b) How much time is required in still water for the same length swim? S (c) Intuitively, why does the swim take longer when there is a current?

If she flips the coin upwards with an initial velocity of 5 m/s:a) How high does the coin rise?b) How long does it take to get to this point?c) How long does it take for the coin to reach the bottom of the well?d) What is the velocity when the coin hits the bottom of the well?
An Object is pushed on a flat surface with an initial velocity of 1.2 m/s and speeds up at a rate of 0.60 m/s^2. a) What is the object’s velocity at a distance of 5m? b) How long and how far will the object to attain a velocity of 10.0 m/s?
A river has a steady speed of 0.570 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. (a) If the student can swim at a speed of 1.00 m/s in still water, how long does the trip take? s (b) How much time is required in still water for the same length swim?
she decelerates at 3.00 m/s?. She reaches the ground with a speed of 4.00 m/s. a) How long is the parachutist in the air? b) At what height does the fall begin?
A girl is standing at the edge of a cliff 100. m above the ground. She reaches out over the edge of the cliff and throws a rock straight upward with a speed 8.00 m/s. a) How long does it take the rock to hit the ground? b) What is the speed of the rock the instant before it hits the ground? Please type answer
A river has a steady speed of 0.650 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.50 m/s in still water, how long does the trip take (swimming up and down in the current)? sIf the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.) s

You are standing at rest at a bus stop. A bus moving at a constant speed of 5.00 m>s passes you. When the rear of the bus is 12.0 m past you, you realize that it is your bus, so you start to run toward it with a constant acceleration of 0.960 m>s 2 . How far would you have to run before you catch up with the rear of the bus, and how fast must you be running then? Would an average college student be physically able to accomplish this?
