Question

two bodies of equal masses move with the uniform velocity v and 3v respectively find the ratio of kinetic energy​

Answer 1

Answer:

referring to the attachment

Answer 2

Answer: The ratio of the kinetic energies =1:9

Explanation:

As We Know

Velocity of the first body =v

Mass of second body =m

Velocity of second body =3v

Hence, The ratio of kinetic energies of the two bodies =  

Kinetic energies of second body/

Kinetic energies of first body
