a banana peel is dropped from rest down a shaft. 6.2 s later the sound of the banana hitting the ground is heard. how deep is the shaft

i think:

v1= 0m/s

a=9.8m/s^2

i'm reallu stuck on this one.. don't know where to go from here.

is this the relationship?Diane_ said:

d=v1t+ 1/2 at^2?

That's the one. Note that one term drops out completely, and you have a relatively easy solution.

so i'm guessing v1t drops out since v1 = 0m/s. so i just use plug into d=1/at^2 to solve?Diane_ said:That's the one. Note that one term drops out completely, and you have a relatively easy solution.

That would do it.

When we were working on kinematics, we worked on a similar problem, but the problem also stated the speed of sound...

If not, then it seems like a relatively easy problem to solve once you write down all the variables and choose the right kinematics equation to use.

I am, however, bothered by the choice of "banana peel". Not only would I expect air resistance to be important for a falling banana peel, I would be surprized if you could hear one hitting the bottom at all!
