Answer: The energy of dog is [tex]3.4\times 10^3J[/tex]
Explanation:
The energy which a body possesses by virtue of being in motion is called as kinetic energy.
[tex]K.E=\frac{1}{2}\times mv^2[/tex]
m = mass of body in kg
v = speed of body in m/s
[tex]K.E=\frac{1}{2}\times 30\times 15^2[/tex]
[tex]K.E=3375kgm^2s^{-2}=3375J[/tex]
Thus kinetic energy of dog is [tex]3.4\times 10^3J[/tex]
