Thank you for your question!
You must use the formula that calculates the total energy of an object, which includes both potential and kinetic energy:
$$ E_m = E_p + E_k $$
Legend:
• Em: total mechanical energy
• Ep: potential energy
• Ek: kinetic energy
$$ E_p = mgh $$
Legend:
• m: mass (kg)
• g: gravitational constant (=9.81)
• h: height (m)
$$ E_k = \frac{1}{2}mv^2 $$
Legend:
• v: speed (m/s)
This webpage of the Alloprof website explains potential and kinetic energy:
