(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ball is dropped from the roof of a building. An observer looking outside the window sees the ball just outside. If the window is 3.99 m tall and the ball is in view for 0.897 s, how far below the roof is the bottom of the window?

2. Relevant equations

"Kinematics Equations

average velocity:

vave=Δx/Δt

average acceleration:

aave=Δv/Δt

Uniform Acceleration:

vave=(vi+vf)/2

Three key variables (displacement, time, velocity) lead to three key relationships relating each pair:

velocity & time:

v=v0+at

displacement & time:

x=x0+v0t+(1/2)at2

velocity & displacement:

v2=v20+2aΔx"

3. The attempt at a solution

I do not know how to even start this question from..

For example, what equations to use or what numbers do I need to get in order to solve this question.

Please help me with this one guys, thank you very much!
