Answer:

Step-by-step explanation:
Acceleration is second derivative of distance and are related as:

Integrating both sides w.r.to t

Using initial value

We have to calculate the distance covered in time interval [0,5], so:
![\int\limits^5_0 \frac{ds}{dt}=\int\limits^5_0 {\frac{1}{t+2}} \, dt\\\\s(t)=[ln|t+2|]^5_0\\\\s(t)=ln|5+2|+ln|0+2|\\\\s(t)=(ln|7|+ln|2|)\,ft](https://tex.z-dn.net/?f=%5Cint%5Climits%5E5_0%20%5Cfrac%7Bds%7D%7Bdt%7D%3D%5Cint%5Climits%5E5_0%20%7B%5Cfrac%7B1%7D%7Bt%2B2%7D%7D%20%5C%2C%20dt%5C%5C%5C%5Cs%28t%29%3D%5Bln%7Ct%2B2%7C%5D%5E5_0%5C%5C%5C%5Cs%28t%29%3Dln%7C5%2B2%7C%2Bln%7C0%2B2%7C%5C%5C%5C%5Cs%28t%29%3D%28ln%7C7%7C%2Bln%7C2%7C%29%5C%2Cft)
Answer:
196
Step-by-step
Step 1: the last number of 38,416 is 6. <u>6 is not a perfect square.</u>
Step 2: because 6 is not a perfect square, split the number up and add each digit together:
3 + 8 + 4 + 1 + 6 =<u> 22</u>
<u>2 + 2 </u>= 4
Step 3:
the digital root of 38,416 is 4.
4 is in the list of digital roots that are always perfect squares. We can conclude that 38,416 could be a perfect square!
Step 4: find all the factors:
1 x 38,416 2 x 19,208 4 x 9,604 7 x 5,488 8 x 4,802 14 x 2,744 16 x 2,401 28 x 1,372 49 x 784 56 x 686 98 x 392 112 x 343 <em><u>196 x 196</u></em>
Underlined above is the factor combination that makes 38,416 a perfect square. A number can only be a perfect square if the product of two exactly the same numbers is equal to the original number.
