Two bodies of different masses $m_1$ and $m_2$ have the same kinetic energy. If $p_1$ and $p_2$ are their respective momenta,find the ratio $p_1 : p_2$.

Two bodies of mass $4 \,g$ and $25 \,g$ are moving with equal kinetic energies. The ratio of the magnitude of their linear momentum is:

The momentum of an object increases by $50\%$. By what percentage will its $K.E.$ increase?

What is the kinetic energy of an object with a mass of $3 \ kg$ and a momentum of $2 \ Ns$?

$A$ body of mass $8\,kg$ and another of mass $2\,kg$ are moving with equal kinetic energy. The ratio of their respective momenta will be.

In a ballistics demonstration,a police officer fires a bullet of mass $50.0 \; g$ with a speed of $200 \; m s^{-1}$ into soft plywood of thickness $2.00 \; cm$. The bullet emerges with only $10 \%$ of its initial kinetic energy. What is the emergent speed of the bullet?
