1. The problem statement, all variables and given/known data An 18-g rifle bullet traveling 230 m/s buries itself in a 3.6kg pendulum hanging on a 2.8-m-long string, which makes the pendulum swing upward in an arc. Determine the horizontal component of the pendulum's displacement. 2. Relevant equations MaVa1 + MbVb1= MtVt2 k.e.= 1/2mv^2 p.e.= mgh 3. The attempt at a solution I can find the velocity of the pendulum, but not the displacement: 230 m/s * .018= 4.4 kg m/s 4.4 kg m/s / 3.6018 kg = 1.15 m/s (speed of the pendulum with bullet after collision) I just dont know how to find the component of the horizontal displacement. Any help would be greatly appreciated.
