. You drop a single coffee filter of mass 1.7 g from a very tall building, and it takes 52 s 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 five of these coffee filters. What was the upward force of the air resistance while this stack of coffee filters was falling at terminal speed? c. Again, assuming that the stack reaches terminal speed very quickly, about how long will the stack of coffee filters take to hit the ground? (Hint: Consider the relation botwoon nood and the force of oir rocictanco 1
