An object has momentum $p$ and kinetic energy $E$. If its momentum becomes $2p$,then its kinetic energy will be:

$A$ ball of mass $2\,kg$ and another of mass $4\,kg$ are dropped together from a $60\,ft$ tall building. After a fall of $30\,ft$ each towards the earth,their respective kinetic energies will be in the ratio of:

$A$ light body of momentum $P_L$ and a heavy body of momentum $P_H$,both have the same kinetic energy,then:

The kinetic energy of a man is half that of a boy whose mass is half that of the man. If the man increases his speed by $1 \ m/s$,his kinetic energy becomes equal to that of the boy. What is the initial speed of the man?

$A$ particle of mass $m_1$ moves with velocity $v_1$ and another particle of mass $m_2$ moves with velocity $v_2$. Both have the same momentum,but their kinetic energies are $E_1$ and $E_2$ respectively. If $m_1 > m_2$,then:

If the kinetic energy of a body becomes four times its initial value,then the new momentum will
