A hunter on a frozen, essentially frictionless pond uses a rifle that shoots 4.20 g bullets at 975 m/s. The mass of the hunter (including his gun) is 68.5 kg, and the hunter holds tight to the gun after firing it. a) Find the recoil velocity of the hunter if he fires the rifle horizontally. b)Find the recoil velocity of the hunter if he fires the rifle at 58.0 above the horizontal.
