Homework Help Overview

The problem involves a roof tile falling from a building and the time it takes to pass a window of known height. Participants are tasked with determining the height above the window from which the tile falls.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the application of Newton's equations of motion and question the validity of directly calculating velocity from the height and time without considering the motion's acceleration.

Discussion Status

The discussion is ongoing, with some participants suggesting specific equations to use while others caution against oversimplifying the calculations. There is no explicit consensus on the approach yet, but various methods are being explored.

Contextual Notes

Participants are navigating the constraints of the problem, including the time duration for the tile's passage and the height of the window, while also considering the implications of using kinematic equations.

Homework Statement


A roof tile falls from rest from the top of a building. An observer inside the building notices that it takes .20s for the tile to pass her window, whose height is 1.6m. How far above the top of the window is the roof?


Homework Equations


just having trouble determining how to solve.


The Attempt at a Solution

Are you familiar with Newton's equations of motion?
 
try v2-u2=2as
v=u+at
s=ut+1/2at2

where u=v0

2 will be used find out which

Remember you can't just use 1.6/0.2 to calculate the velocity. One of the equations hav0c provided can be used to calculate the velocity at the top of the window. Another to work out the distance from roof to top of window.
