Two bodies of masses $\mathrm{m}$ and $4 \mathrm{m}$ are moving with equal Kinetic energies. The ratio of their linear momentum is

A vertically projected body has its energy

A body $\text{'}A\text{'}$ and another body $\text{'}B\text{'}$ have the same $K.E.$ of translation. Then momentum

The $K.E.$ of a body is doubled. Its momentum will

The following four particles have same momentum which one has maximum $K.E.$?
