Two bodies of unequal masses have the same momentum. Which one will have more kinetic energy?

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

If the momentum of a body of mass $m$ is increased by $20 \%$,then its kinetic energy increases by: (in $\%$)

$A$ graph between kinetic energy $K$ and momentum $P$ of a particle is plotted as shown in the figure. The mass of the moving particle is ........ $kg$.

Three bodies $P$,$Q$ and $R$ have masses $m \ kg$,$2m \ kg$ and $3m \ kg$ respectively. If all the bodies have equal kinetic energy,then which body/bodies will have the greater momentum?

$A$ particle is initially at rest on a frictionless horizontal surface. $A$ force of constant magnitude and direction is applied to it. The graph shows the work done $(W)$ on the particle versus its speed $(v)$. If no other horizontal forces act on the particle,what should the graph look like?
