ANSWER: Option C
EXPLANATION: When firing a gun, the gun’s momentum will be equal to the bullet’s momentum.
So, if Mg —> mass of the gun
Vg —> recoil speed of the gun
Mb —> mass of the bullet
Vb —> speed of the bullet
Then, Gun momentum = Bullet momentum
Mg × Vg = Mb × Vb
Make Vg the subject of the formula and insert the values of the others to arrive at your answer.
