\frac{Ec_{1}}{Ep_{1}}=\frac{m\times v_{1}^{2}}{2\times m \times g \times h_{1}}\\ \\
\frac{Ec_{1}}{Ep_{1}}=\frac{ v_{1}^{2}}{2 \times g \times h_{1}}\\ \\ \\
Ec_{1}+Ep_{1}=Ep\\ \\
\frac{m \times v_{1}^{2}}{2}+m \times g \times h_{1}=m \times g \times h\\ \\
v_{1}^{2}=2 \times g \times h-2 \times g \times h_{1}\\ \\
v_{1}^{2}=2 \times g \times(h-h_{1})\\ \\ \\
