Answer:
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
[tex]K = 0.5 mv^2[/tex]
As the speed is same so the ratio of the kinetic energies is same as the ratio of masses.
[tex]\frac{K_{accord}}{K_{Trcuk}} =\frac{m_{accord}}{m_{Trcuk}}\\\\\frac{K_{accord}}{K_{Trcuk}} = \frac{1}{3}[/tex]
