in 8.43s, 168 bullets strike and embed themselves in a wall. The bullets strike the wall perpendicularly. Each bullet has a mass of 5 x 10-3 kg and a speed of 931 m/s. (a) What is the average change in momentum per second for the bullets? (b) Determine the average force exerted on the wall. (c) Assuming the bullets are spread out over an area of 2.76x 10-4 m7 obtain the average pressure they exert on this region of the wall.
