Question

Bullet when fired at a target has its velocity decreases to 50% after penetrating 30 cm into it then the additional thickness it will penetrate in cm before coming to rest is​

Answer 1

Answer:

firstly you have to find the acceleration in first case taking the final velocity equal to 50% of the initial velocity

and after you find the acceleration

take final velocity= 0 as the bullet had stopped after hitting the target and the initial velocity in this case would be the final velocity of the first case

and from here you would find the distance the bullet had travelled

hope you understand ☺️
