If h=0.01 then the average velocity over the time period [1,1.01] equals___m/s. If h=0.001 then the average velocity over the time period [1,1.001] equals___m/s. If h=0.0001 then the average velocity over the time period [1,1.0001] equals___m/s. (b) Using the results of p...
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...
Actually, the velocity at any instant t is V(t) = dS(t)/dt = 5x1.7cos(1.7t). Thus V(1) = 5x1.7 cos(1.7x1) = -1.0952 (m/s). This is very close to the case h=0.0001.
When analyzing velocity vs time graphs there are two key points we must take into account: The graph's slope at any given point yields the instantaneous acceleration. The area between the graph and the x-axis equals the displacement.
Velocity is the change in position (x), or distance, over time. If you know the change in position and the amount of time taken to complete the journey, you can determine velocity. If you have two of these variables, you can always solve for the third. T

This process is repeated over and over again. For larger particle Reynolds numbers, the buoyancy-equals-drag equation (5.3) with the friction coefficient given by the Ergun equation (5.4) can be rewritten as follows in terms of an Archimedes number, Ar, that is, similar to the Grashof ...
When using this formula, it's important to measure displacement in meters and time in seconds. 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 ...
