A balloon having mass 
is filled with gas and is held in hands of a boy. Then suddenly it gets released and gas starts coming out of it with a constant rate. The velocity of the ejected gas is also constant (2 m/s) with respect to the balloon. Find out the velocity of the balloon when the mass of gas is reduced to half
