Phone call can you stop the freefall

When the floor of the elevator makes a sudden stop due to hitting the base of the lift shaft, you too will make a sudden stop. If you jump, will it help? You jump at just the right moment, and lift off just as the elevator hits the floor. At this moment, you are to our camera moving upwards with what we will call your jump speed.

At this crucial moment, just before it hits the ground, the elevator is falling with a certain elevator speed. Because of your leap, you are falling more slowly than the elevator. The speed at which you hit the floor of the suddenly stopped elevator is the elevator speed minus your jump speed.

As an equivalent, we can think in terms of height: how high was the elevator when it fell, and how high can you jump? Falling one storey 3m : timed right, you hit the ground as if you fell from 80cm.

Falling three storeys 9m : you hit the ground as if you fell 4. Typically, upon initially exiting the airplane at 10, feet you will feel a bit of a speed increase, as it will take around seconds for you to reach terminal velocity.

The amount of time you fall when skydiving is going to depend on two things: how long it takes you to reach terminal velocity and the altitude you jump from. At Skydive St. Louis , you will make your jump from 10, feet which is nearly two miles above the earth. From this height, you will fall for 45 seconds.

More likely, you'd hit your head on the ceiling and land badly, exacerbating your injuries. Another suggestion holds that you should stand with your knees bent to absorb the impact, like a skydiver. Theoretically, your legs would flex as you and the elevator touched down, spreading your body's deceleration over a longer period impact force is proportional to speed and mass, and inversely proportional to time and stopping distance the longer the time spent stopping, the less the force.

The effectiveness of this approach at high speeds, however, remains unclear, and research shows that you would likely be subjecting your knees and legs to greater injury risk at low speeds. This approach also keeps your body parallel to the lines of force, which increases the chance of bone breakage as you crumple to the floor under high load. With these factors in mind, the consensus view holds that your best bet is to lie flat on your back on the floor and cover your face and head to guard against debris.

Hitting the ground floor in this position spreads the force of impact across your body; it also orients your spine and long bones perpendicular to the impact direction, which will better protect them from crushing damage. Your thinner bones, like ribs, might still snap like twigs, but you're picking your poison here.

Making gravy without the lumps : With your body positioned flat on the floor, your soft tissues including your brain and organs absorb the full impact.
