Question

Two bodies of equal masses with the
uniform velocities v and 3r. Find the
ratio of their kinetic energy​

Answer 1

Answer:

ANSWER

Mass of first body =m

Velocity of the first body =v

Mass of second body =m

Velocity of second body =3v

The ratio of kinetic energies of the two bodies =
