Answer 1

$\large\underline{ \underline{ \sf \maltese{ \: Given:- }}}$

• Height = ( s ) = $\sf\green{ 0.8m}$
• Intial Velocity ( u ) = $\sf\green{ {0}m \: s^{ - 1} }$
• Final Velocity ( v ) = $\sf\green{ ? }$
• Acceleration = ( g ) = $\sf\green{{10}m \: s^{ - 2} }$

$\begin{gathered}\begin{gathered}\begin{gathered}: \implies \underline\blue{ \boxed{\displaystyle \sf \bold\orange{\: {v}^{2} \: - \: {u}^{2} \: = \: 2gS}} }\\ \\\end{gathered}\end{gathered}\end{gathered}$

$\qquad \quad {:} \longrightarrow \sf{\sf{ {v}^{2} \: - \: {0}^{2} \: = \: 2\: × \: 10 \: × \: 0.8}}$

$\qquad \quad {:} \longrightarrow \sf{\sf{ {v}^{2} \: = \: 16 \: }}$

$\qquad \quad {:} \longrightarrow \sf{\sf{ v\: = \: \sqrt{16} \: }}$

$\qquad\quad {:} \longrightarrow \underline \red{\boxed{\sf{ V \: = \: 4 m \: {s}^{ - 1} }}}$

$\begin{gathered}\begin{gathered}\begin{gathered}: \implies \underline\blue{ \boxed{\displaystyle \sf \bold\orange{\: Momentum \: = \: M \: × \: V }} }\\ \\\end{gathered}\end{gathered}\end{gathered}$

$\quad {:} \longrightarrow \sf{\sf{Momentum \: = \: 10kg\: × \:4 m \: {s}^{ - 1} }}$

$\qquad\quad {:} \longrightarrow \underline \red{\boxed{\sf{ \: Momentum \: = \: 40Ns }}}$
