Since the plane appears to be going in one direction (toward San Diego) in a straight line, you can assume that the change in position equals distance. Plug your known variables into the distance formula: \({\bigtriangleup x} =(150mph)(3.5h) = 525 miles\) TL;DR (Too Long; Didn't...
It is reasonable to assume that the echo time equals the time necessary for the radio wave to travel from the Earth to the Moon and back (that is, neglecting any time delays in the electronic equipment). Calculate the distance from Earth to the Moon given that the echo time was 2.56 s...
2. Since velocity times supply of money equals the gross domestic product, the money supply can be expected to grow comparatively rapidly to support GDP growth. 3. They panted with suspense as velocity sucked Di several meters underwater and the ferocious maelstrom whipped his figure to and fro...
Distance equals rate times time, but our problem is that the rate keeps changing. We must therefore approximate our answer. One way to approach the problem is to subdivide the time span into n intervals, to pick a time ti between each xi−1 and xi, and use g(ti) as the approximate...
1 yields the number of times the point oscillates each second, which is the frequency of the wave. Multiplying the wave's frequency by its wavelength, which is its physical length, yields the velocity of the wave. The relationship can be expressed as velocity equals frequency times wavelength....
In the position-time graph below identify the time or times at which the instantaneous velocity is zero. The figure shows the acceleration versus time graph of a particle moving along the x-axis. Its initial velocity is v_{0_{x = 8.00 m/...
For simplicity's sake, let's assume that old Gary ran to the west in a perfectly straight, 12-meter (32.8-foot) line, so his displacement equals the distance he traveled. We also know that it took him three seconds to cover the gap between his starting and ending points. Therefore, ...
In the position-time graph below identify the time or times at which the instantaneous velocity is zero. How do you find the instantaneous velocity on a position-time graph? Can you have zero acceleration and nonzero velocity? Use a graph to explain. ...
The swirl component of the predicted mean velocity, < uθ > is also in good agreement with the measurements to the same downstream distance. The predicted mean radial velocity, < ur >, however, is in poor agreement with the measurements close to the centreline in the near burner region, ...
equals 2π. substituting the values in the equation, we get \(\begin{array}{l}\omega =\frac{16\pi\,radians }{1\,s}=16\pi \,rads^{-1}\end{array} \) therefore, the angular velocity of the tire is 16π rads -1 . related articles: angular speed angular acceleration angular ...
