Brave Soldier

Classical Mechanics Level pending

A soldier with a machine gun, falling from an aeroplane gets detach from his parachute. He is able to resist the downward acceleration if he shoots 40 bullets a second at the speed of 500 meter/second. If the weight of the bullet is 49 gram, what is the weight of the man with the gun?

Ignore resistance due to air and assume acceleration due to gravity g=9.8 meter/second square.
