Question

A bullet of mass 50 gram is fired from a gun it leaves the barrel with the velocity of 100 Ms in 0.1 seconds calculate the power expanded by the gun firing the bullet

Answer 1

Hope this will be helping you.

Answer 2

M1=4kg (mass of gun) and M2=0.010kg (mass of bullet)

V1=? ( velocity of gun) and V2=400m/s (velocity of bullet

M1*V1=M2*V2

4*V1=0.010*400

V1=4/4

V1=1m/s

Hope this will helping you
