The kinetic energy is 1452 joules
The energy an object has as a result of motion is known as kinetic energy. In physics, a kinetic term is the portion of the Lagrangian that is bilinear in the fields (and for nonlinear sigma models, they are not even bilinear), and typically contains two derivatives with respect to time (or space); in the case of fermions, the kinetic term typically contains just one derivative.
formula of kinetic energy is 1/2 mv^2
Since v is not given
thus v = [tex]\sqrt{2gh}[/tex]
On substituting the values h = 0.5 m and g = 9.8 m/s^2
v = [tex]\sqrt{2 *0.5 * 9.8 * 0.5}[/tex]
v = [tex]\sqrt{4.9}[/tex]
v = 2.2 m/s
Thus kinetic energy = 1/2 × 600 × 2.2²
kinetic energy = 1452 joules
