For a forensics experiment, a student decides to measure the muzzle velocity of the pellets from his BB gun. She points the gun horizontally. On a vertical wall a distance 47.3 m away from the gun, a target is placed. The shots hit the target a vertical distance 0.10 m below the gun's barrel. What is the initial speed of the pellets?
