Question

Quizplus · Accepted Answer

The average force on the machine gun can be calculated using the formula:

Average force = (mass of bullet x velocity of bullet x number of bullets fired per second)

Plugging in the given values:

Average force = (0.060 kg x 600 m/s x 6 bullets/s) 
Average force = 216 N

Therefore, the correct answer is E.
