Hello, in this question we are given that the barrel of a gun is 12 .7 cm long.
00:10
This is 12 .7 cm.
00:14
Alright, here initial velocity is 0 and the final velocity is 360 meter per second.
00:24
Alright, the mass of the gun is given to us that is 8 grams.
00:31
We need to calculate the time required to travel this distance and acceleration over this distance.
00:38
So as we know that we will assume constant acceleration, okay, for the time when it is inside this.
00:48
So v square minus u square is equal to 2a .s we can use because over here, u is known zero.
00:55
S is known to us that is 12 .7 centimeters, 0 .1 to 7 meters.
01:02
So acceleration we can calculate.
01:04
So over here this would be 360 square is equal to 2 into 0 .127 into a...
