Detailed Solution

A horse of mass

210 kg

and a dog of mass

25 kg

run at the same speed. The horse will have higher kinetic energy.
"Kinetic energy is the energy associated with the movement of objects. Kinetic energy is directly proportional to the mass of the object (

m

) and the square of its velocity (

v

).”

K . E = \frac{1}{2} m v^{2}

The speed of both the horse and the dog is the same. The kinetic energy of the horse will be higher as it has more mass than the dog since kinetic energy is directly proportional to the object's mass.
