(a) A soccer player kicks a rock horizontally off a 39 m high cliff into a pool of water. If the player hears the sound of the splash 3.02 s later, what was the initial speed given to the rock (in m/s)? Assume the speed of sound in air is 343 m/s. 20.013 V 19.8 m/s (b) What If? If the temperature near the cliff suddenly falls to 0°C, reducing the speed of sound to 331 m/s, what would the initial speed of the rock have to be (in m/s) for the soccer player to hear the sound of the splash 3.02 s after kicking the rock? 18.969 18.8 m/s

During a routine flight in 1956, test pilot Tom Attridge put his jet fighter into a 20 dive for a test of the aircraft’s 20 mm machine cannons. While traveling faster than sound at 4000 m altitude, he shot a burst of rounds.Then, after allowing the cannons to cool, he shot another burst at 2000 m; his speed was then 344 m/s, the speed of the rounds relative to him was 730 m/s, and he was still in a dive. Almost immediately the canopy around him was shredded and his right air intake was damaged.With little flying capability left, the jet crashed into a wooded area, but Attridge managed to escape the resulting explosion. Explain what apparently happened just after the second burst of cannon rounds. (Attridge has been the only pilot who has managed to shoot himself down.)
An airplane has wings, each with area 3.85 m2, designed so that air flows over the top of the wing at 248 m/s and underneath the wing at 226 m/s. Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" and the total mass of the craft is 300 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of gravity on the surface of Mars is about 3.8 m/s2. ______________m2
A man is driving his 4.5 m long automobile at 90 kph when the traffic signal in front of him changes to yellow. He is 55 m. from the intersection when he applies the brakes after 1.5 second reaction time. If the car can decelerates at a rate of 3.2 m/s2, at what velocity will he be moving when he reaches the intersection? If the yellow light is 5 seconds long, where will the man be when the light turns red? Assuming he will continue through at the speed found in part when the light changes to red. How long will the light have red when he clears the intersection having a width of 20m? Answer the problem and show complete solution please
Two planes approach each other head-on, each has a speed of 785 kph and they spot each other when they are initially 11 km apart. How much time do the pilots have to take evasive action?
The maximum flow rate of standard shower heads is about 3.5 gpm (13.3 L/min) and can be reduced to 2.75 gpm (10.5 L/min) by switching to low-flow shower heads that are equipped with flow controllers. Consider a family of four, with each person taking a 5-min shower every morning. City water at 15°C is heated to 55°C in an electric water heater and tempered to 42°C by cold water at the T-elbow of the shower before being routed to the shower heads. Assuming a constant specific heat of 4.18 kJ/kg·°C for water, determine (a) the ratio of the flow rates of the hot and cold water as they enter the T-elbow and (b) the amount of electricity that will be saved per year, in kWh, by replacing the standard shower heads by the low-flow ones.

On a warm summer day (29 ∘C∘C), it takes 4.70 ss for an echo to return from a cliff across a lake. On a winter day, it takes 5.10 ss . The speed of sound in air is v≈(331+0.60T)m/sv≈(331+0.60T)m/s, where TT is the temperature in ∘C∘C. What is the temperature on the winter day?

A room is 6.00m wide by 8.00 m long by 3.50 m tall and has an air conditioning vent that is 20.0 cm by 30.0 cm pushing air into the room. If the air in the room is replaced every 45.0 min by the air vent, what is the speed of the air coming out of the vent in meters per second?
The answer is supposed to be v=2.56m/s but I'm not sure how to write out the problem.
When a foreign object lodged in the trachea forces a person to cough, the diaphragm thrusts upward, causing an increase in pressure in the lungs. This is accompanied by a contraction of the trachea, making a narrower channel for the expelled air to flow through. For a given amount of air to escape in a fixed time, it must move faster through the narrower channel than the wider one. The greater the velocity of the airstream, the greater the force on the foreign object. X-rays show that the radius of the circular tracheal tube contracts to about two-thirds of its normal radius during a cough. According to a mathematical model of coughing, the velocity v of the airstream is related to the radius r of the trachea by the equation v(r) = k(ro – r)r², 1 srsro where k is a constant and ro is the normal radius of the trachea. The restriction on r is due to the fact that the tracheal wall stiffens under pressure and a contraction greater than 1 is prevented (otherwise the person would…
