experts pls ..can u check this...? this takes some imagination..?

Question

now imagine theres a point A at height of 40 metres . now from that point a thin non elastic lace (thread) starts to materialize(magically orignate) and run down and hits the ground due to gravity. the lace keeps on appearing and its like endless. now when it appears at point A its velocity is zero but it gets jerked up to a velocity . now what would be the vellocity of the lace when hits the ground after runnin down 40 metres. AIR RESISTANCE IS TAKEN AS ZERO. here gravity is acting on the vertical length of the lace which is forty metres. according to me the lace can have a maximum velocity of only 20 m/s. which is less than 28 m/s when u drop something from a height of 40 metres..

now for 1000 metres of lace (thread ) to run down originating from that point A, how long will it take..>? hope ppl get my question

heres anotherway of pttin the question.......

ok forget that that point A. take some 1000 metres of chain or lace to a table which is forty metres high . and now throw down one end of lace or chain. remember the lace is neatly arranged and not etangled . now one starts running down ad hits the ground and begins to pull down the rest of the chain which is at a height of 40 metres on top the table. it ill take some time for the whole length(1000m) to run down. relate both the descriptions to get a clear picture . could you answer my question now.?

Answer 1

What was wrong with my last answer to this question?

Answer 2

Well, gravity has a force of 9.8 meters per second, so if it falls down 40 meters, theoretically, it would be traveling at 39.2 meters per second.

After 6 seconds, it would be traveling at 627.2 meters per second, so it would take between 6 and 7 seconds to hit the ground if the chain was 1000 meters from the ground.

Answer 3

wow very confusing if you ask me!!

Answer 4

um no

Answer 5

not possible
