2. A bullet has a mass of $2.60\mathit{g}$ and a muzzle velocity of $355{\mathit{ms}}^{-1}$. It can penetrate eight $1$-$\mathit{m}$ pine boards, each with a thickness $0.25$ $\mathit{m}$. What is the average stopping force exerted by the wood, as shown in the figure?

 

 

 

Answer:   $\mathit{N}$

Matrix:

Identify the correct matrix type.

 

Piecewise Function

Graph $\mathit{f}\left(\mathit{x}\right)$ to evaluate $\underset{\mathit{x}\to 3^{-}}{lim}\mathit{f}\left(\mathit{x}\right)$.

 

\[ f(x)=\left\{\begin{align*} &9 x-4 & x\lt 3\\ &25 &\text{ if } x=3\\ & x^3 & x\gt3 \end{align*} \right. \]

 

Enter the exact answer.
