You are not providing sufficient information for an answer. Is this object initially stationary? Is it falling to Earth? If so, it is accelerated at a rate of 32 feet per second per second (ignoring air resistance, which will actually make a huge difference). The question then becomes: When? Are you asking what its speed will be upon impact? With air resistance, something called "terminal velocity" comes into play: http://en.wikipedia.org/wiki/Terminal_velocity

What is the numerical ratio of a velocity to speed of an object?
Velocity is an object's Speed + Direction. For example, a cannon ball fired up at 45o to the ground may have a speed of 1000 ft/sec. However, its forward Velocity is:(1000 ft/sec) x (Sine 45o) = (1000 ft/sec) x (.707)= 707 ft/secSo, the ratio of the horizontal Velocity to the instantaneous Speed of the object is the SINE value of the angle of motion relative to the Horizontal axis.But you have to remember that there is a Vertical component of the object's Speed as well. In this case, the ratio is the COSINE 45o , which happens to be .707 as well. So the ball is going forward at 707 ft/sec, and upward at 707 ft/sec. at the same time.
Does the speed of falling objects increase at a constant rate?
The speed of an object falling towards the earth will increase because the gravitational force on the object will accelerate it at a rate of 9.8 m/s² (32.2 ft/sec2). So the speed of a falling body can be calculated by the simple formula: v=u+at Where v = current vertical speed u = vertical speed when it began to fall a = acceleration t = time since it began to fall All of this describes how gravity works. If an object doesn't behave according to this description, the reason is that it's falling through air, which tries to slow it down. (Think of a parachute.) Where there is no air, falling objects behave exactly this way. Notice that the mass or weight of the object doesn't appear anywhere in the math. Where there is no air, all objects, no matter what they weigh, including feathers, rocks, airplanes, sheets of paper, and parachutes, fall with the same acceleration, and every object that falls from the same height hits the ground at the same speed.
What is the average velocity of a free falling object during a 10 s interval?
Acceleration of gravity = 32.2 ft/sec2If the object started from rest, i.e. nobody threw it down, thenInitial velocity = 0Final velocity = (10 x 32.2) = 322 ft per sec.Average = 1/2 ( Vi + Vf ) = 161 ft per sec.
What happens to the velocity of objects moving upward?
The following description covers the region near the surface of the earth ... the neighborhood we live in. It also talks about objects that are just coasting, i.e. no strings attached, no propellers, jets, rockets etc. An object moving upward with no force on it other than gravity will 'decelerate', that is, its speed will decrease at the rate of 32 ft per second slower every second, until its upward speed is zero. From that instant, it will begin falling downward, just as if it had been dropped from that height, and its downward speed will begin to grow, at the rate of 32 ft per second faster every second.
What is the speed of a 380 acp bullet falling straight down?
Falling, and not tumbling end over end, the bullet will accelerate (due to gravity) at 32 ft per second- per second- until it reaches the terminal velocity- limited by air resistance- around 300 mph. If tumbling end over end, more air resistance, less speed- about 225 mps MAXIMUM.
Integer for 28000 ft above sea level?
+28000 FT
How do you convert 28000 square feet into square meters?
Answer: 1 ft² = 0.092903 m² so, 28000 x 0.092903 = 2601.285 m²
The distance that a free falling object falls is directly proportional to the square of the time it falls (before it hits the ground). If an object fell 91 ft in 2 seconds how far will it have fallen?
The answer is 91 ft, of course!
How do you calcalate the speed of an object?
Distance divided by time.For example..( 300 ft. x 3600 seconds ( 1 hour ) = 1,080,000 ft. / 5280 ft. ( 1 mile ) = 204.5455 mph )An object travels 300 ft in 1 second, the object is travelling at 204.5455 Mph.

How many cubic feet in 28000 gal?
28,000 US gallons equates to 3,743.1 cubic feet.

Does the speed of a solid increase while falling under the action of gravity?
yes 9.81 m/s2 or 32.2 ft/s2
What is the speed of an object weighing 80 pounds dropped from 7 feet?
it strikes the ground at a velocity of 17.9 ft/s
Is falling a verb?
Yes falling is a verb; it is an action. For example: The man is falling 300 ft.
If a man parachutes from 5000 ft and another from 2500 ft which man will be falling faster when he reaches the ground?
They will both reach terminal velocity before reaching the ground, and will have the same speed (assuming identical parachutes etc.)
