We have to initially find the Kinetic difference,  

The formula for Kinetic difference is,

K.E{tex}=\frac{1}{2} \times m \times u^{2}{/tex}

{tex}=\frac{1}{2} \times 5 \times 10^{2}{/tex}

{tex}=\frac{1}{2} \times 5 \times 100{/tex}

{tex}=5 \times 50{/tex}

K.E = 250 \ J

The, Potential energy of the body is 250 J, when it reaches the highest point.

Loss in K.E = gain in P.E

→ P.E = 250 J

And the formula for potential difference is,

{tex}PE =m \times g \times h{/tex}

{tex}250=5 \times 10 \times h{/tex}

{tex}250=50 \times h{/tex}

{tex}h=\frac{250}{50}{/tex}

{tex}h = 5 \ m{/tex}
