A 150 gram bullet is fired from a 3.0 k.g gun...?
A 150 gram bullet is fired form a 3.0 k.g gun. If the bullet is traveling with a velocity of 460 m/s, how fast does the gun recoil towards the hunter?

Conservation of momentum:
Initial momentum = 0
= final momentum = mgun vgun - mbullet vbullet
Solve for the recoil speed of the gun:
vgun = vbullet mbullet / mgun
They give you the bullet's speed and the masses. Plugnchug.

Vr = Vb*(Mb/Mg) = 460*.15/3 = 23 m/s
