when looking at a velocity vs. time graph, how can one determine the total distance traveled as well as the displacement?
The following formula relates the distance S (in feet) traveled by a vehicle during an emergency stop to the time T (in seconds) it takes to arrive at a complete stop: s(t)=16t^{2} At the...
A high-pressure water sprayer operates at 2 gal/min. If the diameter of the opening on the nozzle is 0.025 in, what is the velocity of the spray? Answer in MPH
The full question: h = -16t2 - 80t + 1000 The equation above expresses the approximate height h, in feet, of an object t seconds after it is thrown vertically downward...
A water balloon is tossed into the air with an upward velocity of 25 ft/s. Its height h(t) in ft after t seconds is given by the function h(t) = − 16t^2 + 25t + 3. After...
A 27.8 gram mass oscillates on the end of a spring and its motion can be described by: (1.5 )sin (21.4 t ) [here the units are standard, meters and seconds] What are the following for...
A police car is driving past an observer sitting by the side of the road, what happens to the wavelengths of the siren as measured by the observer while the police car approaches to when he goes away...
At very fast car races the sound of the engine as a car approaches is much different than when it passes you. How fast would the car need to be going to have the change in frequency be one...
A pop bottle style instrument is played being open at one end closed at the other, if two successive frequencies, 350 Hz and 490 Hz, are produced, what is the fundamental frequency, and what harmonic...

We have discussed in class that Kepler posed his groundbreaking theory that planets travel in elliptical orbits about the sun, the importance of the conics was affirmed. Also The...
this is a questions about a lighthouse. the lighthouse is 175 feet tall, the beam of light shines up to 25 miles off the coast, and it rotates through one revolution per 15 seconds. it has a...
Driving slowly down a two-lane highway a large transport truck passes me going the same way as I am. As he does physics flashes before my eyes, and I think Bernoulli’s principle with pressure and...

In considering density and buoyancy, a helium balloon floats in air even as wood floats on water. A father was bringing home balloons for a party and had attached the balloons to the seat of a van...
The new blade on my table saw has a radius of 15.0 cm. My table saw has a maximum speed of 3750 rpm. If it takes 2.50 seconds to get up to this final speed, what is the tangential velocity of the...
sitting in a tree 25 feet above the ground, your younger brother listens to your MP3 player. You ask him to give it to you, and he throws it to the ground at a speed of 20 feet/second. How long does...
