If velocity is constants there is no acceleration therefore acceleration will equal zero.
thrust force getting from the burning of mass should balance the weight of the rocket
here thrust force is given as

now by force balance we can say

now plug in all values in this



so rate of mass burning per second will be 5600 kg per second in order to lift up the rocket
