A) 1800 N
B) 2000 N
C) 2200 N
D) 2850 N
Correct Answer: A
Solution :
Key Idea: The bullet comes to rest inside the block, hence final velocity is zero. Let m be mass of bullet, travelling with initial velocity of 120 m/s (u). It comes to rest after travelling a distance of (0.12 m = 5) inside the block. Since, it comes to rest the final velocity (y) is zero. From equation of motion, we haveYou need to login to perform this action.
