accord and a track have the same speed of 30 metre per second if their masses are in the ratio of 1 is to 3 find the ratio of the Kinetic energies ​

The ratio of kinetic energy of accord to the truck is 1 : 3.  

Explanation:

Speed, v = 30 m/s

Ratio of mass of accord to truck = 1 : 3

The kinetic energy is given by

As the speed is same so the ratio of the kinetic energies is same as the ratio of masses.

less than one you can't create energy
