Dixie Holland · Answer 1

1) F1

Explanation:

As the air resistant force depends on the speed of object and its orientation as it falls, it does not depend on the mass of the object. Therefore, air resistant force on 1 coffee filter is the same as the air resistant force on 3 coffee filters.

Three nested coffee filters fall, quickly reaching a terminal speed of ~ 1.7 m/s. If the air resistance force on a single falling coffee filter was F1, how large is the air resistance force on the three falling filters? 1) F1 2) 3*F1 3) (1/3) * F1 4) not enough information
