A hunter on a frozen, essentially frictionless pond uses a rifle that shoots 5.00-g bullets at 1,075 m/s. The mass of the hunter (including his gun) is 75.0 kg, and the hunter holds tight to the gun after firing it. Find the "magnitude" of the recoil velocity (m/s) of the hunter if he fires the rifle at 65.0° above the horizontal.
