Question

A bullet of mass 40gm is fired from a gun of mass 8kg with a velocity of 800 m/s, calculate the recoil velocity of gun

please guys answer this question without any spam please ​

Answer 1

Explanation:

mass of the bullet is 40 gm : convert to kg

1 g = 1/1000 kg

40 g = 40 / 1000 kg

let's keep it as 0.04( mb)

mass of the gun = 8 kg (mg)

velocity of the bullet = 800m/s (vb)

recoil velocity be v ¹

formula to find the recoil velocity is

v¹ = - mb * vb / mg

v¹ = - 0.04 * 800 /8

v¹ = - 32/8

v¹ = - 4 m/s

I think so this is ur answer... Hope it helps you !!! Mark as brainliest please
