two bodies with kinetic energy in the ratio 1:4 are moving with equal linear momentum. Then what is the ratio of their masses?

Question

anonymous · Answer

What are the standard expressions for (magnitude of) linear momentum and kinetic energy, of a body of mass m and speed v ?

anonymous · Answer

the equation connecting momentum and kinetic energy is give by
$$e=p^2/2m$$

anonymous · Answer

right, and this is all you need to find the mass ratio, knowing the two bodies have equal momenta and one has 4 times the kinetic energy of the other
