2kg

Explanation:

As the rocket is falling with a downward force of 20N
Also as the rocket is in air only force due to gravity of earth must be acting on the rocket
:.20=mg
=>20=m×10
=>m=2kg

Note: Here the value of g is taken to be 10ms^-2 for convenience. However for precise calculations g=9.8ms^-2 can be taken.
