Answer:
Einstein extended the rules of Newton for high speeds. For applications of mechanics at low speeds, Newtonian ideas are almost equal to reality. That is the reason we use Newtonian mechanics in practice at low speeds.
Explanation:
<em>But on a conceptual level, Einstein did prove Newtonian ideas quite wrong in some cases, e.g. the relativity of simultaneity. But again, in calculations, Newtonian ideas give pretty close to correct answer in low-speed regimes. So, the numerical validity of Newtonian laws in those regimes is something that no one can ever prove completely wrong - because they have been proven correct experimentally to a good approximation.</em>

Answer:
V = 2.8 m/s
Explanation:
It is given that,
Mass of falcon, 
Mass of dove, 
Initial velocity of falcon, 
Initial velocity of dove, 
When the falcon catches the dove, the momentum remains conserved. Using the formula for the conservation of momentum as :
V is the velocity after impact
V = 2.8 m/s
So, their velocity after the impact is 2.8 m/s. Hence, this is the required solution.
What is happening to this sound is that it’s vibrating over and over.
