A bullet of mass 180g is fired horizontally into a fixed wooden block with a speed of 24m/s.
If the bullet is brought to rest in 0.4 seconds by a constant resistance,
calculate the distance moved by the bullet in the wood.
~~~~~~~~~~~~~~~~~~~~~~~
We have uniformly decelerated movement with the initial speed of 24 m/s
and the final speed of 0 m/s after 0.4 seconds
So, we can calculate the deceleration value "a": it is a = = 60 m/s^2.
Now we can calculate the distance to stop
= = = 4.8 meters. ANSWER
Solved, with full explanations.
The mass of the bullet of 180 g, given in the post, is irrelevant to the problem.
