Question

a boy and a man running with same speed have different Kinetic energies energies​

Answer 1

Explanation:

A boy and a man running with the same speed have different kinetic energies

A boy and a man running with the same speed have different kinetic energiesA running man has the same kinetic energy as that ofa boy of half his mass. The man speed up by 2ms-1 and the body changes his speed by xms-1 so that thekinetic energies of the boy and the man are again equal.....

Answer 2

A boy and a man running with same speed have different Kinetic energies because their speed is same and mass is different.
