The answer would be 1200m/s

The initial velocity of the bullet was 3.5m per sec because on a frictionless surface a bullet can't be stopped as there is no force opposing the bullet and as the bullet must be fired in certain velocity, we can say that the initial velocity of the bullet was 3.5mper sec.
