Explanation:
Assuming the English system of mass and weight is the same as the Imperial system, the measurements are:
• 1 pound (lb) = 16 ounces (oz)
• 2,000 pounds (lbs) = 1 ton (T)
I think that's everything?
Answer:
The answer is "between 20 s and 30 s".
Explanation:
Calculating the value of positive displacement:
![\ (x_{+ve}) = \frac{1}{2} \times 15 \times 20 \\\\](https://tex.z-dn.net/?f=%5C%20%28x_%7B%2Bve%7D%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%2015%20%5Ctimes%20%2020%20%5C%5C%5C%5C)
![= \frac{1}{2} \times 300 \\\\= 150 \\\\](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20300%20%5C%5C%5C%5C%3D%20%20150%20%5C%5C%5C%5C)
Calculating the value of negative displacement upon the time t:
![(x_{-ve}) = \frac{1}{2} \times 5 \times 20- 20(t-20) \\\\](https://tex.z-dn.net/?f=%28x_%7B-ve%7D%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%205%20%5Ctimes%2020-%2020%28t-20%29%20%5C%5C%5C%5C)
![= \frac{1}{2} \times 100- 20t+ 400 \\\\= 50- 20t+ 400 \\\\](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20100-%2020t%2B%20400%20%5C%5C%5C%5C%3D%2050-%2020t%2B%20400%20%5C%5C%5C%5C)
![\to X= X_{+ve} + X_{-ve} \\\\](https://tex.z-dn.net/?f=%5Cto%20X%3D%20X_%7B%2Bve%7D%20%2B%20X_%7B-ve%7D%20%5C%5C%5C%5C)
![\to 150 - 50 -20t+400 =0\\\\\to 100 -20t+400 =0 \\\\\to 500 -20t =0\\\\\to 20t =500 \\\\\to t=\frac{500}{20}\\\\\to t=\frac{50}{2}\\\\\to t= 25](https://tex.z-dn.net/?f=%5Cto%20%20150%20-%2050%20-20t%2B400%20%3D0%5C%5C%5C%5C%5Cto%20100%20-20t%2B400%20%3D0%20%5C%5C%5C%5C%5Cto%20500%20-20t%20%3D0%5C%5C%5C%5C%5Cto%2020t%20%3D500%20%5C%5C%5C%5C%5Cto%20t%3D%5Cfrac%7B500%7D%7B20%7D%5C%5C%5C%5C%5Cto%20t%3D%5Cfrac%7B50%7D%7B2%7D%5C%5C%5C%5C%5Cto%20t%3D%2025)
That's why its value lie in "between 20 s and 30 s".
