Having some conceptual trouble with this problem: "a falling object travels one-fourth of its total distance in the last second of its fall. what height was it dropped from? " would someone me set this one up?

Explanation:

Let the falling object took "n" seconds to reach the ground and it travels H height

So we will have

now we know that it covers one fourth of total height in last second

So we can say that it will cover 3H/4 distance in (n-1) seconds

so we will have

now from above two equations

Now we have

close lines strong magnet less close weaker

the higher the current the higher the mag field around it the higher the influence on the compass
