Let's see that would put 2-3 feet between you and a mass. Once you reached the height of your jump you would be again falling at a maximum rate and you would fall into the bottom of the elevator. Laying down on the floor of the elevator would be an approximation of a seat belt where some of the energy from the fall would be absorbed by the elevator itself. Allowing yourself 3 feet height to bash into the elevator floor only provides the energy damage of falling three feet PLUS the damage from the fall of the elevator. Sounds like minimally more damage to me.

The coin will remain unmoved. The falling elevator is equivalent to gravity-free space such as in a space station. However, it is very difficult to release a coin without imparting a little velocity to it. Therefore it will drift, but in an arbitrary direction.

B.....take a look at several of the TV shows recently showing trips on the Vomit Comet or various other "free fall" planes across the world....When they free fall, everything and every object "floats".....Now note your questions states "you RELEASE a coin" not you "Throw a coin or you flip a coin".....Thus B applies because that coin is falling as fast as you are and no more , no less

The answer is c the elevator has more mass and is going to fall at a higher speed than the coin.

hmmm I would say it would go straight down with you. So I guess the answer would be a. The reason for that is because gravity is still in affect even if you are free falling because gravity is pooling you down and since coin has mass it will also fall down, but I believe that you will land b4 the coin because you got more mass. So my final answer is a. drops straight down

in any elevator when its accelerating downwards a pseudo force of the same acceleration is acting in the upwards direction....so net acceleration=(g-a)
in this case g=a(since its free fall)
s=ut+1/2at^2
a=0,u=0;
s=0+0=0;
so total distance travelled is 0
so it will stay at same height .
(B)

b. it appears to remain at the same height because it is falling at the same rate you are.

b.
Since the coin is already moving at that speed it will stay there like you will.
