$\begin{array}{l}
\,\,\,\,\,\,\,\,\,Components\,of\,momentum\,parallel\
to\,the\,wall\,add\,each\,other\,and\,commponents\
of\,momentum\,in\,the\,prependicular\,to\,\
the\,wall\,are\,opposite\,to\,each\,other.\,\
Therefore\,change\,of\,momentum\,is\,final\
momentum\, - \,initial\,momentum\
i.e,.\,(mv\sin 	heta \,after\,collision\
 - ( - mv\sin 	heta )\,before\,collision)
\end{array}$

$\begin{array}{l}
\,\,\,F 	imes t = change\,in\,momentum\
\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \,2mv\sin 	heta \
	herefore \,\,F = \frac{{2mv\sin 	heta }}{t}\
\,\,\,\,\,\,\,\,\,\, = \frac{{2 	imes 0.5 	imes 12 	imes \sin {{30}^ \circ }}}{{0.25}} = 48 	imes \frac{1}{2} = 24\,N
\end{array}$

A $0.5\, kg$ ball moving with a speed of $12\,m/s$ strikes a hard wall at an angle of $30^o $ with the wall. It is reflected with the same speed at the same angle. If the ball is in contact with the wall for $0.25$ seconds, the average force acting on the wall is ........... $N$
