$A$ light and a heavy body have equal kinetic energy. Which one has a greater momentum?

If a light object (mass $M_1$ and velocity $V_1$) and a heavy object (mass $M_2$ and velocity $V_2$) have the same kinetic energy,then which of the following is true regarding their momenta ($P_1 = M_1 V_1$ and $P_2 = M_2 V_2$)?

The kinetic energy of a body moving along a straight line varies with time as shown in the figure. The force acting on the body is:

If the velocity of a body is twice its previous velocity,then its kinetic energy will become:

Express momentum in terms of mass and kinetic energy.

Two bodies of masses $m_1$ and $m_2$ have equal kinetic energies. If $p_1$ and $p_2$ are their respective momenta,then the ratio $p_1:p_2$ is equal to
