A 3.00-g bullet is fired horizontally into a 10.0-kg block of wood suspended by a rope from the ceiling.  The bullet becomes embedded in the wood, and, as the result, the block swings up in an arc, like a ballistic pendulum, rising 3.00 mm above its original position.  Which of the following is the closest to the initial speed of the bullet? Group of answer choices a. 235 m/s b. 24.3 m/s c. 75.0 m/s d. 811 m/s e. Cannot be determined since the heat generated in the collision is       unknown
