Question

The terminal velocity of water as it falls is 10 m/s. Assuming that the water falls constantly at this rate, how long will it take the water to fall from the height you found above? ______________ seconds

Answer 1

Explanation:

Equation for Terminal Velocity

At terminal velocity, Fnet = 0. Thus the drag force on the skydiver must equal the force of gravity (the person's weight). Using the equation of drag force, we find mg=12ρCAv2 m g = 1 2 ρ C A v 2 . Thus the terminal velocity vt can be written as vt√2mgρCA v t 2 m g ρ C A .
