You drop a single coffee filter of mass 1.7 grams from a very tall building, and it takes 51 seconds to reach the ground. In a small fraction of that time the coffee filter reached terminal speed.
(a) What was the upward force of the air resistance while the coffee filter was falling at terminal speed?
(b) Next you drop a stack of 6 of these coffee filters. What was the upward force of the air resistance while this stack of the coffee filter was falling at terminal speed?
