Homework Statement
A machine gun fires 22 g bullets horizontally at 260 m/s at a constant rate of
40 bullets/s. (a) If the bullets embed themselves in a thick wooden door, what is the average force
exerted on the door? (b) If the bullets hit a steel door and rebound elastically, what is the average
force exerted on the door?
Homework Equations
F = ma
Vf = Vi + at
The Attempt at a Solution
The door shouldn't experience any force at all, because the bullets are not accelerating horizontally. Is this correct?
