A horizontal rifle is fired at a bull's-eye. The muzzle speed of the bullet is 745 m/s. The barrel is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.020 m below the center. What is the horizontal distance between the end of the rifle and the bull's-eye?

can someone solve?

how long does it take for the bullet to fall .020m?

h= 1/2 g t^2
now, having time t,

distance=horizontalvelocity*time
solve for distance.
