Question

two bodies of equal mass moving with a velocity of v and v3 respectively find itz kinetic energy​

Answer 1

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 =KineticenergiesofsecondbodyKineticenergiesoffirstbody

                                                                         =21m(3v)221mv2=29mv221mv2

                                                                         =91

The ratio of the kinetic energies =1:9
