Answer 1

Answer:Self-Defense is more than knowing how to fight back again a physical attack.

Explanation:Participation in self-defense classes encourages you to think in terms of options

and choices, develops your awareness and assertiveness skills and provides

practice for physical self-defense techniques. A good self-defense class will  expand the way you think about violence prevention, help you deal with your  fears and enable you to feel more empowered in your life.  With so many programs, how would you know which ones will best equip you to respond to or avoid an attack?  To find out more, examine our F.A.Q., Criteria and Philosophy, and Self-Defense  Program sections.

neighborhoods, schools, and communities.

Answer 2

$\begin{gathered}\begin{gathered}\pink{ \frak{Given}} \begin{cases} \sf \: initial \: velocity \: (u) = 0 \: ms ^{ - 1} \\ \\ \sf \: final \: velcity \: (v) = 20 \: ms ^{ - 1} \\ \\ \sf \: mass\: (m) = 500 \: kg \\ \\ \sf \: distance \: (s) = 25 \: m\end{cases} \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\underline{\boldsymbol{According\: to \:the\: Question :}} \\\end{gathered}\end{gathered}$

AccordingtotheQuestion:

As we know that,

$\begin{gathered}\begin{gathered}\\ : \implies \displaystyle \sf \: v ^{2} - u ^{2} = 2as \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \:(20) ^{2} - (0) ^{2} = 2 \times a \times 25 \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \:400 - 0 = 2 \times 25a \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \:400 = 2 \times 25a \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: \frac{400}{2} = 25a \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \:a = \frac{200}{25} \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\:a = 8 \: ms ^{ - 2} }} }\\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\\ \dashrightarrow \displaystyle \sf \: Force = mass \times Acceleration \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\dashrightarrow \displaystyle \sf \: Force = 500 \: kg \times 8 \: ms ^{ - 2} \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\dashrightarrow \displaystyle \sf \: Force = 4000 \: kg.ms ^{ - 2} \\ \\ \\\end{gathered}\end{gathered}$

$\dashrightarrow \underline{ \boxed{\displaystyle \sf \: \bold{ Force = 4000 \: N}}}⇢$
