An 8.0-g bullet with a speed of 800 m/s is shot into a wooden block and penetrates 20 cm before stopping. What is the average force of the wood on the bullet? Assume the block does not move

The answer to your question is F = 16 N

Explanation:

Data

mass = 8 g

vo = 800 m/s

distance = 20 cm

force = ?

vf = 0 m/s

Process

1.- Calculate the acceleration of the bullet

Formula

  a = (vf² - vo²)/2d

Substitution

  a = (0 - 800)/2(0.2)

  a = -800/0.4

  a = 2000 m/s²

2.- Convert 8g to kg

           1000 g   1 kg

                 8 g   x

             x = (8 x 1)/1000

             x = 0.008 kg

3.- Calculate the force

Formula

      F = ma

Substitution

      F = (0.008)(2000)

Simplification and result

      F = 16 N

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
