If the kinetic energy of a body increases by $0.1\%$,the percent increase of its momentum will be .............. $\%$

Two particles have masses $m$ and $4m$, and their kinetic energies are in the ratio $2:1$. What is the ratio of their linear momenta?

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:

In the non-relativistic regime,if the momentum is increased by $100\%$,the percentage increase in kinetic energy is (in $\%$)

Two bodies of masses $m$ and $2m$ have the same momentum. Their respective kinetic energies $E_1$ and $E_2$ are in the ratio:

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?
