# How many feet does it take to reach terminal velocity?

###### Wiki User

1) Terminal velocity is never quite reached; a falling object will get closer and closer to terminal velocity. You can put some arbitrary limit, for which you can say that "for all intents and purposes, terminal velocity has been reached", for example, 95%, or 99%, of terminal velocity.

2) The actual terminal velocity varies for different objects. A feather will approach its terminal velocity almost instantly; a heavy object, without much surface area (for example, a steel ball) will have to fall more seconds (and more meters or feet), before it is anywhere close its terminal velocity.

Well the average terminal velocity ofr an average sized jumper is 120mph. I fall at 120mph and fall 10,000 feet in 45/50 seconds so I guess about 213 feet per second.

That's innanswerable, take for instance rain, which comes in many different sizes, it's terminal velocity is reached when the force of friction becomes equal to the force gravity is applying on it. But as water groups together in different sizes and therefore when falling has different levels of friction it falls at different speeds and so the terminal velocity of water depends on the amount of water

If you assume that the punter is in space, where there is no gravity nor air resistance, it will take 2/3 second.

2, Gravity and Friction (aka wind resistance). The body will reach terminal velocity when the air it is passing through creates enough friction so that it equals the force of gravity therefore stopping any further acceleration.

Depends on the rifle shooting it. The M16A2 rifle has a muzzle velocity of ~3100 feet per second. A rifle with a shorter barrel will have less velocity.

To convert time to distance you must also know the velocity.

There are there are 8 stages, Tropical Resort, Sweet Mountain, Starlight Carnival, Planet Wisp, Aquarium Park, Asteroid Cloister, Terminal Velocity and Game Land/Sonic Simulator. Each with 2 Acts, 3 side missions and a boss, aside from Terminal Velocity which has one act and a boss.

Velocity (or Speed) = Distance &divide; Time Toni's speed is therefore 100 &divide; 20 = 5 feet per second. Distance = Velocity x Time In 25 seconds, Toni walks, 5 x 25 = 125 feet.

The answer depends on what gas the balloon contains, its initial velocity and the forces - gravity, buoyancy, cross-wind - acting on it.

The Boston airport contains 4 terminals. Terminal A, terminal B, terminal C, and terminal E.

There are three types of velocity. (1)Uniform velocity. (2) Variable velocity. (3) Instantaneous velocity.

Average sheet of toilet paper being 4 inches square, you would need approximately 900000 squares to reach 300000 feet.

I live in western Canada. Many of our Pines reach 180 and more feet.

I used to do a bit of parachuting back in the 70s and terminal velocity was always reckoned to be about 120 mph (200 kph) achieved after about 12 seconds in free fall. But different objects will have different TVs, depending upon how aerodynamic they are. In physics, When an object is in a freefall, and it reaches its terminal speed, there is no net force, and so its acceleration is zero. Going down, the direction of the air resistance is downwards, whereas that of the weight is upwards. Going up, air resistance R and weight W are in the same direction. i.e. downwards. By F=ma, When an object is thrown vertically upwards, at the instant its speed equals this terminal speed on the way up, the magnitude of its acceleration is 20ms-2. the direction is downwards. then by v = u + at, you can easily calculate the terminal velocity in many different cases.
