Speed = (acceleration) times (time)
Acceleration = gravity = 9.8 meters (32.2 feet) per second2
Speed = 10g = 98 meters (322 feet) per second

How fast in miles per hour would an object fall after 3 seconds?
At the end of 3 seconds, a falling object is falling at 65.8 mph faster than when it was released, ignoring air resistance.
If a stone falls past a bird on a ledge moving at 4 m/s, how fast will the stone be moving?
D. 36 m/s
Is it true that the thing that affects how fast it falls is the objects surface area?
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).
How fast is a rock moving after falling for 2.3 seconds?
Acceleration due to gravity is approx 9.8 metres/second2 So after 2.3 seconds, the velocity of the rock is 9.8*2.3 = 22.54 metres/second
How fast would you be going after falling 50 feet?

If a stone falls past a bird on a ledge moving at 4 meters per second how fast will the stone be moving just before it hits the ground below 9 seconds later?
92.2m/s
Why do the satellite not fall while revolving around the earth?
They do fall. But they're traveling fast enough so that the surface of the Earth falls away from them as fast as they are falling. Same thing that keeps the Earth from falling into the sun.

If a stone falls past a bird on a ledge moving at 4ms how fast will the stone be moving just before it hits the ground below 9 seconds later?
A 92.2 m/s V = (4 m/s) + (9.8 m/s²) (9 s) V = 92.2 m/s

Explain why a man using a parachute falls through air slowly while a stone falls through air very fast?
When an object falls through air, it experiences air resistance. This air resistance is a force that opposes the object's motion. The amount of air resistance an object experiences depends on the object's shape, size, and speed. A man using a parachute falls slowly because the parachute creates a large amount of air resistance. A stone falls very fast because it has a small amount of air resistance.
If you drop a rock from a great height about how fast will it be falling after 5 seconds neglecting air resistance?
The object will be falling at 49 m/s.This is solved by multiplying the force of gravity (9.8 m/s) by the time you're calculating (5s).
How fast does angel falls fall?
very fast how fast can u fall
A 10kg bowling ball rolls off the table and strikes the ground if the ball is in the air for 8 seconds how fast is the ball moving when it hits the ground?
As is typical of this type of question, I am going to assume that the falling bowling ball is not affected by the friction of the air through which it falls. The formula for velocity is v = gt where g is acceleration due to gravity, 9.8m/sec2 After 8 seconds, the ball is falling at v = 9.8m/sec2 * 8 sec = 78.4 m/sec. If it really has a mass of 10kg, it's not a bowling ball. Bowling balls are limited to about 7.27 kg.
