Question

A gun of mass 1 Kg fires a bullet of mass 10g with a speed of 100 m/s. What is the recoil velocity of the gun?

Answer 1

Answer:

-1 m/s

its very simple

try it yourself

Answer 2

Thus, the recoil velocity of the gun is 1 m/sec.

Step-by-step process

Given:

Mass of the gun = 1Kg

Mass of the bullet = 10g = 0.01 kg

Velocity of the bullet = 100m/sec

To find: the recoiling velocity of the gun

Using the law of momentum conservation:

$M_{1}V_{1 } = m_{2}v_{2}$

Here, $M_{1}$ = mass of the bullet

$m_{2}$= mass of the gun

$V_{1}$= velocity of the bullet

$v_{2}$= recoil velocity

Putting in the values, we get:

0.01 × 100 = 1× $v_{2}$

1 =$v_{2}$

Result:

Thus, the recoil velocity of the gun is 1 m/sec.
