Answer:
-15 m/s
Explanation:
The computation of the velocity of the 4.0 kg fragment is shown below:
For this question, we use the correlation of the momentum along with horizontal x axis
Given that
Weight of stationary shell = 6 kg
Other two fragments each = 1.0 kg
Angle = 60
Speed = 60 m/s
Based on the above information, the velocity = v is
![1\times 60 \times cos\ 60 + 1\times 60 \times cos\ 60 - 4\ v = 0](https://tex.z-dn.net/?f=1%5Ctimes%2060%20%5Ctimes%20cos%5C%2060%20%2B%201%5Ctimes%2060%20%5Ctimes%20cos%5C%2060%20-%204%5C%20v%20%3D%200)
![\frac{60}{2} + \frac{60}{2} - 4\ v = 0](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B2%7D%20%2B%20%5Cfrac%7B60%7D%7B2%7D%20-%204%5C%20v%20%3D%200)
![v = \frac{60}{4}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B60%7D%7B4%7D)
= -15 m/s
Answer: A
Out of the screen
Explanation:
Using right hand rule, the magnetic force is perpendicular to the plane form by the magnetic field of a charged particle and its speed. Which will be into the screen.
But the negative charged particle moves in the opposite direction of the positive charged particle. Therefore, the magnetic force direction will be out of the screen
1. B- it can cause cirrhosis
2. C- intoxication
3. A- admit to having a problem with alcohol
4. D- binge-drinking
5. A- depressant
6. true
7. false
The process of burning fuel is Combustion
The answer is 2500 newtons. F = M * A, so 500 kg x 5 m/s = 2500 newtons.
