Answer:
13 weeks
Step-by-step explanation:
8×13=104
125-104=21$
This really depends on the fraction; if there are variables in the equation, if they are full numbers,etc. I'd really recommend looking up khan academy on YouTube and that will really help you out!
Answer:
The recoil velocity of the gun is
and is pointing in opposite direction to the velocity of the bullet.
Step-by-step explanation:
Use conservation of linear momentum, which states that the momentum of the bullet (product of the bullet's mass times its speed) should equal in absolute value the momentum of the recoiling gun (its mass times its recoil velocity).
We also write the mass of the bullet in the same units as the mass of the gun (for example kilograms). Mass of the bullet = 0.010 kg
In mathematical terms, we have:
![5\, kg * v= 0.01 \,kg\,* 360\,\frac{km}{h} \\v=\frac{0.01\,*360}{5} \,\,\frac{km}{h}\\v=0.72\,\,\frac{km}{h}](https://tex.z-dn.net/?f=5%5C%2C%20kg%20%2A%20v%3D%200.01%20%5C%2Ckg%5C%2C%2A%20360%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D%20%5C%5Cv%3D%5Cfrac%7B0.01%5C%2C%2A360%7D%7B5%7D%20%5C%2C%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D%5C%5Cv%3D0.72%5C%2C%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D)
