2. A hunter on a frozen, essentially frictionless pond, uses a rifle that shoots a 4.20-g bullet at a speed of 965-m/s. The mass of the hunter and rifle is 73.5-kg, and the hunter holds the rifle tightly as he fires it. Find the recoil speed of the hunter right after firing, if: a) He fires it horizontally; b) He fires it at an angle of 55.0° above the horizontal.
