The thing is the elevator is accelerating so the velocity is not constant.

"What will happen to the people inside?"

They will be squeezed through the vents in the roof of the elevator.

^_Really!

Is English your primary language?

The elevator accelerates faster than gravity?!!??! I suppose if some other force were acting on it then ........... if that were the case - the people would hit the roof because they would (supposedly) be accelerating with gravity..

To really get answers from this question wouldn't it be better to determine the mass of your riders and then calculate the splat velocity? Once your elevator reaches its final destination... end of the ride, so to speak... there are many great tangents to delve into.

Expand your horizons and choose a specific amount of floors (100 is always good to start) and a specific quantity of riders, and then calculate exactly how much of the six surfaces inside would be covered by them after coming to rest.

One could even go further and determine the statistical probabilities on just how many sizes the "test subjects" bones should shatter into.

Someone please remind me to take the stairs.

Nothing. Elevators are equipped with a safety gear that will clamp the car onto the guide rails once the speed exceeds a certain limit.

I know what you're talking about despite the difference in terms...

The people in the elevator will float. It's an inertial reference frame, and all objects (including the elevator) are in free-fall.

_{^{PS: Welcome to the monkey house.}}

If you cut an elevator cable, it accelerates at g, not faster. You can make an elevator accelerate faster, but that takes an external energy source.

If the elevator falls at g, the people float. If it accelerates downward faster than g, the people hit the roof.

If you ask homework questions on here, you'll never learn anything for yourself.
