Answer:
B) The initial momentum is 12 kg*m/s, and the final momentum is 24 kg*m/s
Explanation:
The momentum of an object is given by the product between its mass (m) and its velocity (v):
Let's apply this formula to calculate the initial momentum and final momentum of the ball:
- initial momentum:
- Final momentum:
So, the correct answer is
B) The initial momentum is 12 kg*m/s, and the final momentum is 24 kg*m/s
Air pressure ''Decreases'' with Elevation. So B) would be your answer.
No the speed does not depend on its mass, yes to the second question and yes to the third
