The time it takes to fall 33,000 feet can be calculated using the formula t = √(2d/g), where t is the time in seconds, d is the distance in feet (33,000 in this case), and g is the acceleration due to gravity (32.2 ft/s^2). Plugging in the values, we get t = √(2 * 33,000 / 32.2) ≈ 81 seconds. The speed you would reach can be calculated using the formula v = gt, where v is the final velocity in ft/s, g is the acceleration due to gravity (32.2 ft/s^2), and t is the time in seconds (81 seconds in this case). Thus, the final velocity would be v = 32.2 * 81 ≈ 2,608.2 ft/s.

How fast would a 160 lb man reach from a fifty ft fall?
The speed at which a 160 lb man would hit the ground after a 50 ft fall can be estimated using physics. Ignoring air resistance, he would reach a terminal velocity of about 25-30 feet per second just before impact. Using the formula for free fall, he would take approximately 2.5 seconds to reach the ground, reaching a speed of around 40-45 mph at the moment of impact. However, air resistance would slow him down slightly, so the actual speed may be lower.
What is the reason for rain drops to fall with a constant speed by the time they reach earth?
Raindrops fall with a constant speed due to the balance between gravity pulling them downwards and air resistance pushing back. This equilibrium results in a steady descent speed for raindrops as they fall towards the Earth.
How far do you have to fall to reach 120 mph?
It would take approximately 1,500 feet for an object to reach a speed of 120 mph when free-falling due to the force of gravity.
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.
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)
What happens if water hits terminal velocity?
If water were to reach terminal velocity, it would fall at a constant speed due to the balance between gravity pulling it down and air resistance pushing it up. This means that the water would no longer accelerate and would continue to fall at that maximum speed until it reaches the ground or another surface.
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.
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.
Would someone weights 50kg fall faster than someone who weights 75kg?
No, they would both fall at the same speed.
An object launched from Earth must attain a speed of 7900 m per second to achieve a low orbit What happens if the object its maximum speed is less than 7900m per second?
If the object's maximum speed is less than 7900 m/s, it will not reach a low orbit and will fall back towards Earth due to gravity. To achieve a stable low orbit, an object needs to reach the necessary speed to counteract the gravitational pull and continuously fall towards Earth.
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.
