A bullet is fired from a rifle. If the rifle recoils freely, then the kinetic energy of the rifle is
Less than that of the bullet
More than that of the bullet
Same as that of the bullet
Equal or less than that of the bullet
A bullet is fired from a rifle. If the rifle recoils freely, then the kinetic energy of the rifle is
$E = \frac{{{P^2}}}{{2m}}.$If $P =$ constant then $E \propto \frac{1}{m}$
i.e. kinetic energy of heavier body will be less. As the mass of gun is more than bullet therefore it possess less kinetic energy.
