# Math Help - A ball is dropped off a ledge... (Physics)

1. ## A ball is dropped off a ledge... (Physics)

A ball is dropped off a ledge How far does it fall in the 2nd second?
The answer is 14.7 meters.
Could someone explain why it's 14.7? Shouldn't it be 19.6 meters?

apparently by "in the 2nd second" it means "between time = 1 second and time = 2 seconds"

that yields the desired answer.

the question was vaguely posed.

3. Hello, iamanoobatmath!

There's nothing wrong with your math,
. . but you misread the problem.

A ball is dropped off a ledge.
How far does it fall in the 2nd second?

They want the distance it fell during the 2nd second
. . . . . between $t=1$ and $t = 2$.

(Yes, I agree . . . very sneaky!)
