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 player using a cue accelerates a shuffleboard disk at a constant 7.3m/s2 from rest for 0.65sec. At this point the disk loses contact with the cue and slows down at a constant rate of 2.3 m/s2 until it stops. What is the total distance traversed by the disk?
The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)?
You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground. How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway? Express your answer using one significant figure.
The distance S that an object falls varies directly with the square of the time t. If an object falls 16 feet in one second, how long for it to fall 400 feet? The time required to drive a fixed distance varies inversely as the speed. It takes 1 hr at a speed of 400 km/h to drive a fixed distance. How long will it take to drive the same distance at a speed of 8 km/h?
A fast food restaurant uses a conveyor belt to send the burgers through a grilling machine. If the grilling machine is 1.1m long and the burgers require 2.5min to cook, how fast must the conveyor belt travel? If the burgers spaced 15cm apart, what is the rate of burger production (in burgers/min)?

What is vav,x for the time interval from t = 9.00 s to t = 11.0 s? answer in m/s c. What is vav,x for the interval t = 0 to t = 17.0 s? answer in m/s d. What is the increase in the car’s speed between 10.0 s and 17.0 s?answer in m/s e. How far does the car travel from time t = 10.0 s to t = 19.0 s? answer in m
A red train traveling at 72 miles/hour (mph) and a green train traveling at 100 mph are headed toward one another along a straight, level track. When they are 2500 feet apart, each engineer sees the other's train and applies the brakes. The brakes decelerates each train at the rate of 2.0 meters per second squared. Is their a collision? If so, what is the speed of each train at impact? If not, what is the separation between the trains when they stop? Give the given and solution:
The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)? The same physics was responsible for the noticeable delay in communications signals between lunar astronauts and controllers at the Houston Space Flight Center.
