An attack helicopter is equipped with a 20-
mm cannon that fires 105 g shells in the
forward direction with a muzzle speed of
669 m/s. The fully loaded helicopter has a
mass of 4260 kg. A burst of 133 shells is fired
in a 5.41s interval.
What is the resulting average force on the
helicopter?
By what amount is its forward speed reduced?

force*time=massbullets*velocity
force=massbullets/time * velocity
but the massbullets/time=133*.105/5.41
solve for force.
