## Homework Statement

An elevator ascends with a constant speed of 2.5m/s. A loose bolt drops from the ceiling of the elevator which is 3.0m above the floor.

a) How long does it take the bolt to fall from the ceiling to the floor of the elevator?

b) What are the displacements of the bolt and the elevator floor in this time?

## Homework Equations

constant acceleration (with acceleration equal to gravity at 9.81m/s/s)

## The Attempt at a Solution

I managed to get the first part, with t = 1.08 s, but now I am confused with part B. I am not sure what the displacement of the elevator floor really is (I cannot picture it) and I assumed the displacement of the bolt at this time was the 3m that it fell (that's the value of displacement I used to get the time in the first place) SO now I am quite confused.

Can any one give me a hand?

Thanks!
