A horizontal rifle is fired at a bull's-eye. The muzzle speed of the bullet is 670 m/s. The gun is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.025 m below the center.
a. What is the horizontal distance between the end of the rifle and the bull's-eye?
b. If the target were not in the way, how far would the bullet travel horizontally before hitting the ground?
