A bullet from a gun is fired on a rectangular wooden block with velocity 
. When bullet travels 
through the block along its length horizontally, velocity of bullet becomes 
. Then it further penetrates into the block in the same direction before coming to rest exactly at the other end of the block. The total length of the block is :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
v 2 − − u 2 = 2as
Case 1: 
…
Case 2: 
…
Dividing by , we get
Total length = 24 + 3 = 27 cm
