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:
hi, this is the answer
Explanation:
A horizontal line on a distance-time graph shows no change in distance, therefore there is no motion.
The object is stationary. ...
Constant speed is motion that occurs with the same ratio of distance to time throughout the entire length of the motion.
pls mark this as the brainliest...
