A 0.2-kg bullet is fired into a 1.8-kg pendulum bob as shown in the diagram to the right. The bullet gets stuck inside the pendulum bob after striking it with an unknown initial horizontal velocity. If the pendulum bob is observed to be moving at 10 m/s immediately after the collision, what was the speed of the bullet just before it collided with the pendulum bob? h = ? Vi = ? 100 m/s 90 m/s 75 m/s 50 m/sā
