A solid wooden block resting on a frictionless surface is hit by a bullet. The bullet gets embedded. During this process

A bullet of mass 10xx10^(-3) moving with a speed of 20ms^(-1) hits an ice block (0^(@)C) of 990g kept at rest on a frictionless floor and gets embedded in it. If ice takes 50% of K.E, the amount of ice melted (in grams) approximately is (J=4.2J/cal) (latent heat of ice=80cal/g)
