a machine gun fires 10 bullets persecond into a target. each bullet weights 20 gm and had a speed of 1500 m per second .find the force neccessary to hold the gun in posotion?

Answer 1

Average force = (momentum change)/time
= (bullet mass) x velocity x (10/ second)

Answer 2

10/s * .02 kg = .2 kg/s
force = rate of change of momentum or m a
= change in momentum per second
= .2 kg/s * 1500 m/s
= 300 kg m/s^2 = 300 Newtons

Answer 3

300 Newton but how can solved

Answer 4

300N
