Answer:
44.8 m/s
Explanation:
Use the Initial Speed Formula:
InS = 2(d/t) - Final Speed
InS = 2(55/1,25) - 43.2
InS = 2.44 - 43,2
InS = 88 - 43,2
InS = 44.8 m/s
Answer:
For the first one shown, the answer is Directly Proportional, The second one is Inversly Proportional, and the last is fourtl times the original value
Answer:
![Volume = 6248.48 m^{3}](https://tex.z-dn.net/?f=Volume%20%3D%206248.48%20m%5E%7B3%7D)
Explanation:
Given:
The area of the house ![A = 2050\ ft^{2}](https://tex.z-dn.net/?f=A%20%3D%202050%5C%20ft%5E%7B2%7D)
The height of the house ![h=10\ ft](https://tex.z-dn.net/?f=h%3D10%5C%20ft)
We need to find the volume of a typical house.
Solution:
We find the volume of the house by multiplying the area of the house and height of the house.
![Volume = Area\times height](https://tex.z-dn.net/?f=Volume%20%3D%20Area%5Ctimes%20height)
![Volume = A\times h](https://tex.z-dn.net/?f=Volume%20%3D%20A%5Ctimes%20h)
Area and height of the house are known, so we substitute these value in above equation.
![Volume = 2050\times 10](https://tex.z-dn.net/?f=Volume%20%3D%202050%5Ctimes%2010)
![Volume = 20500\ ft^{3}](https://tex.z-dn.net/?f=Volume%20%3D%2020500%5C%20ft%5E%7B3%7D)
Now we convert the unit from feet to meter.
Divide the volume by 3.2808 for ![m^{3}](https://tex.z-dn.net/?f=m%5E%7B3%7D)
![Volume = \frac{20500}{3.2808}](https://tex.z-dn.net/?f=Volume%20%3D%20%5Cfrac%7B20500%7D%7B3.2808%7D)
![Volume = 6248.48\ m^{3}](https://tex.z-dn.net/?f=Volume%20%3D%206248.48%5C%20m%5E%7B3%7D)
Therefore, the volume of the house is ![6248.48 m^{3}](https://tex.z-dn.net/?f=6248.48%20m%5E%7B3%7D)
Answer:
9 and 3 N
Explanation:
Forces in the same direction sum up to produce the resultant force;
One force subtract the other will give the resultant force when they are in opposite directions;
Lets say one direction is forwards and the opposite backwards;
We have one force, let's say force A, in the forwards direction and another force, force B, acting in the same (forwards) or opposite (backwards) direction;
If B is acting in the same direction, then the resultant force (in this case) will be as follows:
A + B = 12
If B is acting in the opposite direction, then the resultant force will be as follows:
A - B = 6
Summing the two equations will allow us to solve for A:
A + B + (A - B) = 12 + 6
2A = 18
A = 9
Substitute this into either of the above equations and we can solve for B:
(9) - B = 6
B = 9 - 6
B = 3
