Question

A gun of mass ½ t recoils with a velocity of 0.8 m/s while firing a shell of mass 4 kg. calculate the velocity at which the shell leaves the gun.

Answer 1

Hey !!!!    ✴✨✨ Here's your answer ✨✨✴   ______⬇⬇⬇⬇⬇⬇⬇⬇⬇______   Given,  Mass of gun, M=1/2 t=500 kg ( 1 tonne = 1000 kg)  Recoil velocity of gun, V=0.8 m/s  Mass of shell, m=4 kg  Velocity of shell, v=?  Using,  Mass of shell x Velocity of shell=Mass of gun x Recoil velocity of gun  m×v=M×V 4×v=500×0.8 or  velocity of shell,    v=500×0.84/4= 100  m/s (answer)    Hope helps you ✌✌✌!
