    Horatio Leafbottom, a newly-initiated member of Gangster's Union Local #219, was shot in the shoulder at a recent union meeting for refusing to apologize after making strong comments on the topic of the superiority of cats as pets. Luckily, the bullet traveled straight through Leafbottom's shoulder. He will make a full recovery. Because of the chaos at the time, however, Leafbottom cannot make a confident determination of the shooter's identity. Police investigators have narrowed the suspect field to the three candidates who were armed and in the room at the time. Janice Jackson, a small-time software pirate, was found carrying a .38 Special. Aloisus Datarcy, a suspected weapons dealer, was found with a .45 Automatic Colt Pistol (ACP). Merv Redwood, suspected money launderer, was apprehended with a .357 Magnum. All three guns had been fired recently. Neither the bullet nor the shell casing was found at the crime scene. However, based on Leafbottom's testimony, you can pinpoint where in the room Leafbottom was standing when he was shot. Further, the emergency doctor's report indicates definitively that, based on entry and exit wound locations, the bullet emerged from Leafbottom's shoulder with a perfectly horizontal velocity. After passing straight through Leafbottom's shoulder 1.6325 m above the ground, the bullet travelled another 3 m into the wall 1.627m above the ground. FBI Firearm Expert Lorenzo Nofingers has provided you with the following table showing estimated muzzle velocities based on the firearms confiscated from the suspects. Investigators on the scene determined that it took the bullet .0335seconds to travel the distance between the victim's shoulder and the wall. Further, ballistics testing indicates that passing through Leafbottom's shoulder would slow each bullet down to 30% of its initial muzzle velocity.

    To calculate the velocity of the bullet as it hit the wall, you will use the horizontal distance the bullet traveled and the time that investigators calculated it took the bullet to travel between the victim's shoulder and the wall. For this we will use the formula velocity= distance/time (Hint: The horizontal distance is how far the bullet traveled behind Leafbottom) So, would I just do the muzzle velocity divided by .0335 to find the final velocity?

    In quondam days, sequestered from the trivialities of concomitant, prevailing culture, resided a youth for whom mirth was sorely lacking in his daily routine. In truth, the youth named Jack suffered from such an extremity of disconsolation that the gracious expression of even the slightest smirk never once surfaced on his visage. The kith and kin with whom he shared his abode felt distracted by his despondency, and they endeavored in vain to bring him even a moment of felicity.

    and no...dividing velocity by 0.0335 does not give you anything. multiplying muzzle velocity with 30/100 gives final velocity.

    final velocity multiplied by 0.0335 seconds gives distance travelled(3 metres)

    but i dont get how the velocity is "perfectly horizontal" since the bullet hits the wall at point lower that where it hit the shoulder
