# A Horse and a Dog Are Running with the Same Speed. If the Weight of the Horse is Ten Times that of the Dog, What is the Ration of Their Kinetic Energies? - Science

Short Note

A horse and a dog are running with the same speed. If the weight of the horse is ten times that of the dog, What is the ration of their kinetic energies?

#### Solution

Kinetic energy of a moving body is directly proportional to its mass. Hence, if the mass of the horse is 10 times the mass of the dog, then,
"(Kinetic energy)"_"Horse"/"(Kinetic energy)"_"Dog" = 10/1

Is there an error in this question or solution?
