Ignoring air resistance ...
Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second
after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight
makes no difference.

What is the net force of a 7 pound object falling 20 inches?
The net force on a 7 pound object that is falling (accelerating down) is 7 pounds. If it is not falling or moving at a constant speed, it is zero.
Why the air resistance decrease the acceleration on falling object?
Drop a pound of feathers (in a bag) and a pound of lead from a height. The smaller mass of the lead will let it fall faster due to less air resistance, than the greater mass and much greater air resistance of the feathers.
What weighs more a pound of books or a pound of feathers?
The weigh the same. A pound is a pound is a pound no matter what the object is.
How much force are you exerting when you lift a 50 pound dumbbell?
Any force that is more than 50 pounds will lift a 50-pound object. The greater the force is, the greater the object's upward acceleration, and the sooner the object will reach any given height.
How much is 30 shilings in pounds?

What is the net force of a 7 pound object falling 20 inches?

How long does it take for a 200 pound object to fall 692 feet?
If they're not falling through air, then a bean and a battleship both fall 692 feetin 6.556 seconds. The weight of the object makes no difference.If the object IS falling through air, then in order to answer the question, we need toknow the object's shape, size, and volume, plus the temperature, humidity, density,and pressure of the air, at every altitude between the ground and 692 feet.

How many feet will a 100 pound object fall in 7 seconds?
Any object near the surface of the earth, falling without air resistance and under the influence of only gravity, falls 789 feet. (rounded) Its weight makes no difference.
How far does the average object fall before reaching its termanal speed?
For that question, there is no such thing as an "average object". A falling object's terminal speed depends on its weight, dimensions, and shape. It's very different for a 10-pound round rough stone, a 10-pound flat stone, and a bowling ball. And the same exact object may have different terminal speeds, as when a sky-diver makes himself fall faster or slower by getting into different positions.

Why the air resistance decrease the acceleration on falling object?
Drop a pound of feathers (in a bag) and a pound of lead from a height. The smaller mass of the lead will let it fall faster due to less air resistance, than the greater mass and much greater air resistance of the feathers.
