Question

the muzzle velocity of a bullet in 5.56 INSAS rifle in 882 m/s. a sergent holds his rifle facing the sky and shoots a bullet . what is the maximum reachable altitude ? assume g=9.8m/s (hint vA2=uA2*2hg)​

Answer 1

Answer:

5m........is your answer dear. I don't know this is a correct answer or what but I can help you dear.

Answer 2

We will solve this question with the help of Equation of motions i.e.,

$2as=v^{2}-u^{2}$

Given:

$u=882m/s$

$a=-9.8m/s$

On solving, we get:

$2as=v^{2}-u^{2} \\2(-9.8)s=0-(882)^{2}\\ s=39,690m\\s=39.69km$

Therefore, $39.69km$ is the maximum reachable altitutde.
