1. The problem statement, all variables and given/known data A 2.5 g bullet, traveling at a speed of 425 m/s, strikes the wooden block (mass = 215 g) of a ballistic pendulum. (A) Find the speed of the bullet/block combination immediately after the collision. (B) How high does the combination rise above its initial position? 2. Relevant equations initial velocity = (mass1 + mass2 / mass1) * final velocity final velocity = square root of (2 * gravity * final height) 3. The attempt at a solution is the 425 m/s the initial or final velocity?
