363597 A balloon having mass ‘\(m\)’ 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 gases 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. (Neglect gravity and Bouyant force),

Sand from a stationary hopper falls onto a moving conveyor belt at a rate of 5 \(kg\)/\(s\) as in fig. The conveyor belt is supported by frictionless rollers and moves at a constant speed of 0.750 \(m\)/\(s\) under the action of a constant horizontal external force \({F_{ext}}\) supplied by the motor that drives the belt. Find the external force \({F_{ext}}\).
