How much air resistance acts on a falling 100-N box of nails when it reaches terminal velocity?
The air resistance acting on a falling
Answer to Problem 20A
Explanation of Solution
Introduction:
When an object falls with its terminal velocity, then it means that no net acceleration is acting on it or the object moves with a constant velocity.
Since when the object reaches the terminal velocity, the net acceleration of the object is zero. Hence, for the given box of nails, it can be written as,
Where,
Conclusion:
Hence, the air resistance acting on a falling given box of nails, when it reaches terminal velocity, is
