Quizplus · Accepted Answer

The bullet on the Moon will travel a greater horizontal distance due to the lower gravitational acceleration, resulting in a longer flight time. The bullet on Earth will have a shorter flight time due to higher gravity. The velocities at impact will differ because the vertical component of velocity will be greater on Earth due to higher gravity.
