Which is the equation for terminal velocity?
Vt= square root of w/2dACd
Vt =square root of dACd/2w
Vt =square root of 2m/dACd
Vt= square root of 2w/dACd
Vt = square root of 2m/dACd
The correct equation for terminal velocity is:
Vt = square root of (2w/dACd)
Where:
Vt represents the terminal velocity,
w represents the weight of the object,
d represents the density of the fluid,
ACd represents the drag coefficient.
The equation for terminal velocity depends on the context or scenario in which it is being used. Terminal velocity is the maximum velocity an object can reach when falling through a fluid, such as air or water, due to the balance between the gravitational force pulling the object down and the drag force pushing against it.
One commonly used equation for terminal velocity is:
Vt = √(2mg / ρACd)
Where:
- Vt is the terminal velocity,
- m is the mass of the object,
- g is the acceleration due to gravity,
- ρ is the density of the fluid (air or water),
- A is the cross-sectional area of the object, and
- Cd is the drag coefficient.
To determine the terminal velocity using this equation, you would need to know the values of these variables for the specific object and fluid you are considering.
