Refer to the following information for the next eight questions.
We will begin by dropping one coffee filter from the second floor railing. This will provide enough distance for the coffee filter to reach its terminal velocity before it enters the pre-measured drop zone located between the bottom of the second-floor landing and the base of the stairs. Begin timing the coffee filter when it reaches the reference height until it strikes the ground (stair step). Repeat this for a total of three trials. Place your answers in the first data table below.
The coffee filter must be released bottom-side down. Moreover, you are not to give it any extra velocity upon release - just let it fall from rest.
Trial #1 time _____________ Trial #2 time _____________ Trial #3 time ______________
Trial #1 height _____________ Trial #2 height _____________ Trial #3 height ______________
Repeat this procedure with two, then three, then four ….. all the way up to eight filters. Place your rime and height data in the first data chart provided below.
Since terminal velocity is an example of constant velocity, you can then calculate the filter’s rate of fall by using the formula d = rt. Place your AVERAGE rate of fall for each set of filters in the second data table below.
