Question

$a=g$

$u=0$

$v=? ?$

$s=h$

$v^{2}-u^{2}=2 a s$

$\Rightarrow v^{2}=2 g h$

$\Rightarrow \quad v=\sqrt{2 g h}$

$u=0 \cdot 8 \sqrt{2 g

$0.64$

Vedclass · Answer

$a=g$

$u=0$

$v=? ?$

$s=h$

$v^{2}-u^{2}=2 a s$

$\Rightarrow v^{2}=2 g h$

$\Rightarrow \quad v=\sqrt{2 g h}$

$u=0 \cdot 8 \sqrt{2 g h}$

$v=0$

$a=-g$

$s=? ?$

$v^{2}-u^{2}=2 a s$

$\Rightarrow e^{2}-0.64 	imes 2 g h=2(-g)^{5}$

$\Rightarrow 0.64 	imes 2 g  h=2 g S$

$S=0.64 \mathrm{h}$

$A$ ball is dropped from $a$ height $h$. As it bounces off the floor, its speed is $80$ percent of what it was just before it hit the floor. The ball will then rise to $a$ height of most nearly .............. $\mathrm{h}$
