In real life, you would probably exceed 250 MPH, but slow to 120 MPH closer to the ground. This is called "terminal velocity", the velocity at which your drag, bouyancy, and F=mg sum to zero. But this changes as the air density increases. If you want to ignore the atmosphere (like skydiving on the Moon), Then V=gmt; and S=1/2gmt2; S=33000; gm=5.31 ft sec-2; Solve for V

What is the reason for rain drops to fall with a constant speed by the time they reach earth?
They reach their terminal velocity.
Why must spacecraft reach escape velocity to be able to go to space?
a slower speed will not overcome the gravitational pull of the Earth. It would fall back to Earth.
Results for quarters and feathers fall at the same speed?
Quarters and feathers would only fall at the same speed in a vacuum. In air, the quarter would fall faster, as it has less air resistance.
How do different masses fall in a vacuum?
In vacuum, all masses big and small fall with the same acceleration, and reach the same speed in the same amount of time.
What happens to the distance you fall during each second?
If you fall from a very considerable height then initially the distance that you fall will increase with each second that you fall. However, air resistance increases markedly with speed and this causes your acceleration to decrease so that you reach a maximum speed (terminal velocity)
Why a helicopter falling during auto-rotation could reach a terminal speed without the pilot changing any controls?
The helicopter begins to fall because gravity is pulling its weight. As the helicopter accelerates, the air passing past the helicopter creates drag, as the helicopter continues to accelerate the drag Increases until the drag becomes equal to the weight, stopping it from accelerating. Even if the helicopter did not auto rotate it would still reach a terminal speed, however the terminal speed for the non auto rotating helicopter would be a lot higher and the helicopter would take longer to reach this speed.
Which would fall faster in a vacuum a science table or a bar of soap?
In a vacuum they would both fall at the same speed.
Would someone weights 50kg fall faster than someone who weights 75kg?
No, they would both fall at the same speed.
When a object falls what does it reach because of air resistance?
When an object falls, air resistance causes it to reach a terminal velocity. After that, it does not increase the speed of falling, no matter how far it has still to fall.
Two masses fall 3 meters to the ground. If friction is neglected when do they reach the ground?
both masses have the same speed. The acceleration of objects in freefall is independent of mass, resulting in the same speed at the end of a fall. The momentum and energy are proportional to the mass.
What would you find if you cut a really big hailstone in half?
it would fall at a lighter speed
Why falling objects don not move forward with a speed of 17700 mph?
And what makes you think an object would fall, or should fall, precisely at such a speed? How do you get that number? - Anyway, that's not the way our Universe works. Without air resistance, an object that falls downward falls faster and faster - its speed increasing by 9.8 meter/second every second. With air resistance, a falling object will eventually reach a speed at which friction (air resistance) balances the downward force of gravity. This speed is different for different objects.
