to resist the downward acceleration if he shoots 40 bullets a second at the speed of 500 m/s. If the
mass of a bullet is 49 gm, what is the mass of the man with the gun ? Ignore resistance due to air
and assume the acceleration due to gravity g = 9.8 m/s2.

Answer 1

Answer:

75 kg is the answer because I know because

Answer 2

Answer:

We know

mg=nmv

m×9.8=40×500×49

m=

9.8×1000

40×500×49

[49gm = 49/1000 kg]

m=100kg

That is mass of the man along with the gun is 100 kg.
