Question

a bullet of mass 10kg is fired at a speed of 400meter per second from a gun of mass 4kg what is recoil velocity of the gun

Answer 1

Answer:

1000 m/s

Explanation:

From the relation , MV= -mv , where M= mass of the gun , V = velocityof the gun , m = mass of the bullet , v = velocity of the bullet.

4 x V = -10 X 400

THEREFORE , V = - 10 X 400 / 4 = - 1000

HENCE , Recoil velocity of the gun is 1000 m/s
