Question

When the air density is 0 kg/m°(vacuum), how long will it take an object to reach terminal velocity?

a. It reaches terminal velocity immediately.
b. 2 seconds
5 Seconds
d. The object never reaches terminal velocity.

Answer 1

d. The object never reaches terminal velocity.

Step-by-step explanation:

Terminal velocity is the velocity a falling object reaches when the air resistance equals the weight. But in a vacuum, there is no air resistance. So the object never reaches terminal velocity.
