Assume that the small-massed particle is
and the heavier mass particle is
.
Now, by momentum conservation and energy conservation:
![mv = mv_{m} + Mv_{M}](https://tex.z-dn.net/?f=mv%20%3D%20mv_%7Bm%7D%20%2B%20Mv_%7BM%7D)
![mv^{2} = mv^{2}_{m} + Mv^{2}_{M}](https://tex.z-dn.net/?f=mv%5E%7B2%7D%20%3D%20mv%5E%7B2%7D_%7Bm%7D%20%2B%20Mv%5E%7B2%7D_%7BM%7D)
Now, there are 2 solutions but, one of them is useless to this question's main point so I excluded that point. Ask me in the comments if you want the excluded solution too.
![v_{m} = v\frac{m - M}{m + M}\\\\\\v_{M} = v\frac{m + M}{m + M}\\](https://tex.z-dn.net/?f=v_%7Bm%7D%20%3D%20v%5Cfrac%7Bm%20-%20M%7D%7Bm%20%2B%20M%7D%5C%5C%5C%5C%5C%5Cv_%7BM%7D%20%3D%20v%5Cfrac%7Bm%20%2B%20M%7D%7Bm%20%2B%20M%7D%5C%5C)
So now, we see that
and
. So therefore, the smaller mass recoils out.
Hope this helps you!
Bye!
Answer:
it is light
Explanation:
the arrow that says light is on the glass it must be near from tungsten
Answer:
In general solids are easier to transport than liquids, but the above metal example is a valid one and the only other one that comes to mind is that of concrete. It is mixed as a liquid and transported as such, but then sprayed or laid down to dry and form a solid surface or filler.
Explanation:
Answer:
20m/s due east
Explanation:
Given parameters:
Displacement eastward = 200m
Time = 10s
Unknown:
Velocity = ?
Solution:
Velocity is the displacement divided by time;
Velocity =
Velocity =
= 20m/s due east
Kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously. So, A.
