We are given that the mass ratio of two
objects is and their kinetic energy ratio is . We need to find the ratio of their momenta.
Recall the formula for kinetic energy and
momentum
The kinetic energy of an object is given
by:
The momentum of an object is given by:
Express kinetic energy and momentum
We know the kinetic energy ratio:
Substitute the formula for kinetic energy
into this ratio:
Solve for the velocity ratio
We are also given that the mass ratio is
