Answer:
1/6 x 1/5 = multiplication equation
4)
the arrow touches the ground when the heigth is 0
so we need to replace h=0 and solve for t
![\begin{gathered} h=17t-5t^2 \\ 0=17t-5t^2 \\ 0=t(17-5t) \\ 0=17-5t \\ 5t=17 \\ t=\frac{17}{5}=3.4 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20h%3D17t-5t%5E2%20%5C%5C%200%3D17t-5t%5E2%20%5C%5C%200%3Dt%2817-5t%29%20%5C%5C%200%3D17-5t%20%5C%5C%205t%3D17%20%5C%5C%20t%3D%5Cfrac%7B17%7D%7B5%7D%3D3.4%20%5Cend%7Bgathered%7D)
<em>the arrow tuches the ground at 3.4 seconds</em>

![F=m\times a](https://tex.z-dn.net/?f=F%3Dm%5Ctimes%20a)
replacing
![185=m\times13.7](https://tex.z-dn.net/?f=185%3Dm%5Ctimes13.7)
<em>solve for m</em>
![\begin{gathered} m=\frac{185}{13.7} \\ \\ m=13.50 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20m%3D%5Cfrac%7B185%7D%7B13.7%7D%20%5C%5C%20%20%5C%5C%20m%3D13.50%20%5Cend%7Bgathered%7D)
<em>the mass is 13.50Kg</em>
