in passing theough a wooden block 8cm thick the velocity of a beullet reduces from 700m/s to 300 m/s if the mass of the bullet is 10g find the average resitance to penetrate ?

Answer 1

change in momentum = .001 (300 - 700)

time in block = .08/(average speed
= .08 / [(700+300)/2]

Force = change in momentum/time in block

Answer 2

How is some

Answer 3

In passing through a wooden block 8cm thick the velocity of a bullet reduces from 700m/s to 300m/s. If the average to resistance to the penetrate
