You can use these same formulas to calculate a projectile's initial velocity if you know the height it reaches when tossed into the air and the number of seconds that it takes to reach that height. Simply plug those known values into the equations and solve for v0instead of h. References...
I'm currently working on an app whereby I can add multiple velocities to calculate for height and range. I met with an issue where when I want to add legends to numerous graphs with the legend naming like : "36", "42" as they represent the velocity. However, the number of plots are...
To calculate the drag force, it is assumed that the drag coefficient (CD) is typically around 2.2 and that the cross-sectional area (A) of Starlink satellites is approximately 15.45 m2 (Hardy 2020). We attempted to examine the decay of altitude on Starlink satellites using the Two Line ...
This comes quite useful when you are trying to figure out which HVAC units to buy. Here is an example ofhow to select the best ceiling fansbased on CFMs. To demonstrate how to use the CFM calculator to calculate fan airflow, we’ll start by using the calculator. Here are the results:...
When thinking about the impact force of a falling object, you can calculate the energy of the object at its point of impact if you know the height from which it was dropped. This type of energy is known as gravitational potential energy and it is equal to the object's mass multiplied by...
To calculate the electromagnetic fields generated by return strokes, it is necessary to know the spatial and temporal variation of the return-stroke current along the channel. Unfortunately, only the return-stroke velocity and the current generated at the channel base can be measured directly, and ...
How do you calculate sewer capacity? 6.2.1.1 Pipe Capacities The Continuity equation and the Manning equation for steady-state flow can be used to calculate flow in a sewer pipe: Continuity Equation:Q = V*A Where: Q = peak flow, cubic feet per second (cfs). V = velocity, feet per se...
After observing backpackers struggle for years with compass orientation, I am absolutely astonished that dogs can not only calculate declination, but can actually detect small changes in it. Let’s see, for 17 degrees westing, do I subtract or add that to the heading? It’s gotta be add, ...
Note the equation at the bottom of the diagram above: The formula to calculate the voltage out of a voltage divider is:Voltage Out = Voltage In * resistance below the output / total resistanceWe can calculate the voltage out of the voltage divider by multiplying the Voltage in * R2 / (...
Here we show how major rivers can efficiently connect to the deep-sea, by analysing the longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor turbidity currents originated from the Congo River-mouth, with one flow tr
