The mass of the rock is, m = 24 kg

The velocity of the rock is, v = 2 m/s

The kinetic energy of the rock can be given by the formula


K\mathrm{}E\mathrm{}=(1)/(2)mv^2

Substituting the values, the kinetic energy will be


\begin{gathered} K\mathrm{}E.=(1)/(2)*24*(2)^2 \\ =48\text{ J} \end{gathered}
