The kinetic energy of a body is increased by $4$ times. Its momentum will

The kinetic energy of a light body and a heavy body is same. Which one of them has greater momentum?

If the kinetic energy of a body is increased by $300\%$,then the percentage change in momentum will be:

The kinetic energy of a man is half that of a boy whose mass is half that of the man. If the man increases his speed by $1 \ m/s$,his kinetic energy becomes equal to that of the boy. What is the initial speed of the man?

$A$ particle is dropped from a height $h$. $A$ constant horizontal velocity $u$ is given to the particle. Taking $g$ to be constant everywhere, the kinetic energy $E$ of the particle with respect to time $t$ is correctly shown in:

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?
