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?
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`
