A sack of potatoes weighing 200 N falls from an airplane. As the velocity of fall increases, air resistance also increases. When air resistance equals 200 N, the sack's acceleration in meters per second is _________

Respuesta :

Answer:

Zero

Explanation:

weight of  potato sack falls from an airplane is 200 N

Now velocity of fall increases, as increases the air resistance.

The air resistance is equal to 200 N , which is equal to the weight of the sack with potatoes

Then the sack's acceleration in m/s is = 200-200=Zero.

The acceleration here is based on the resistance of the air. if the air resistance is less, the velocity of the sack of potatoes would be high

Sack's acceleration in meters per second is zero
