$\begin{array}{l}
Suppose\,that\,the\,tennis\,ball\,bounces\,\
with\,a\,velocity\,u.\,It\,will\,go\,up,\,its\,velocity\
becomes\,zero.\,If\,h\,is\,the\,hgight\,up\,to\,which\
it\,rises\,on\,the\,hill,\,then\
\,\,\,\,\,\,\,\,\,\,\,\,{\left( 0 ight)^2} - {u^2} = 2\left( { - g'} ight)h\
Where\,g'\,is\,acceleration\,due\,to\,gravity\,\
on\,the\,hill.
\end{array}$

$\begin{array}{l}
	herefore h = \frac{{{u^2}}}{{2g'}}\
{m{since}},\,the\,accleration\,due\,to\,gravity\,on\
the\,hill\,\left( {g'} ight)\,is\,less\,than\,that\,on\,earth\,\
\left( {effect\,of\,height} ight),\,it\,follows\,that\,tennis\
ball\,will\,bounce\,higher\,on\,hills\,than\,in\,\
plains.
\end{array}$

$Assertion$ : A tennis ball bounces higher on hills than in plains.
$Reason$ : Acceleration due to gravity on the hill is greater than that on the surface of earth
