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

If an object has no kinetic energy,it cannot have momentum. Do you agree?

$A$ man who is running has half the kinetic energy of a boy of half his mass. The man speeds up by $1 \,ms^{-1}$ and then has the same kinetic energy as the boy. The initial speed of the boy is

If the linear momentum is increased by $5\%$,the kinetic energy will increase by.......$\%$

Two masses of $1 \,g$ and $4 \,g$ are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is

If the momentum of an object is increased by $100\ \%$,then its kinetic energy increases by ......... $(\%)$ percent.
