Answer:
The correct equation for terminal velocity is:
b. Vt = square root 2m/dACd
Explanation:
Terminal velocity is the maximum velocity that an object can reach while falling through a fluid, such as air. It occurs when the upward force of fluid resistance equals the downward force of gravity, resulting in a net force of zero and no further acceleration.
The equation for terminal velocity involves the square root of the ratio of two quantities: the weight of the object (m) and the drag coefficient (dACd). The weight of an object is given by the mass (m) multiplied by the acceleration due to gravity (g).
The correct equation, Vt = square root 2m/dACd, takes into account both the weight of the object and the drag coefficient. The square root of 2m/dACd represents the equilibrium point where the object's weight is balanced by the drag force, resulting in terminal velocity.
