a 2.8kg gun held 12 degrees above the horizontal shoots a 5mg bullet at a target which is located at the same height above the floor as the gun. If the gun recoils at a velocity of 3.5 m/s, how far away does the target need to be for the bullet to strike the target?

the answer is suppose to be 1.59x10^5m but for some reason I got 1.59x10^13 m?
