The kinetic energy of an object is increased by a factor of 7, by what factor is the magnitude of its momentum changed?

A 9.0-g bullet is fired into a 160-g block of wood at rest on a horizontal surface. After impact, the block slides 7.00 m before coming to rest. If the coefficient of friction between the block and the surface is 0.430, what is the speed of the bullet before impact?
