Drag is passive, therefore it does not act on gravity. Drag is a mechanical resistance to motion. If the motion in question was induced by gravity drag it can impede that motion, but has no effect on the gravity.
hope this helps!
Answer:
The cumulative distance that the bird travel is 13.33 Km
Explanation:
Given that,
Velocity of runner = 3.4 km/hr
Distance = 8 km
Velocity of bird = 17 km/hr
Let x is the distance from the origin where the runner run into the bird
We need to calculate the value of x
Using time of runner and bird
Put the value into the formula
We need to calculate the cumulative distance that the bird travel
Using distance of bird
Put the value into the formula
Hence, The cumulative distance that the bird travel is 13.33 Km
Answer:

Have you ever heard this phrase, "What weighs more, a ton of feathers, or a ton of lead?" The answer is, they weigh the same, however the ton of feathers takes up more space than the ton of lead. So to answer your question, the answer is yes, and no. Depending on what the substance is will determine your answer. I hope that i helped.
Explanation:
Momentum of the system is a constant when there aren't external forces..
So,When first Balls velocity is went down to zero... its momentum is also zero and beacause momentum should be a constant...now second ball must have a momentum of 20 kg * m/s
