An astronaut brings a "Feed the Monkey" demonstration to the Moon. The apparatus contains a cannon that shoots a ball at a stuffed monkey that is dropped at the same time the cannon is fired. On Earth, the astronaut knows that the ball will hit the stuffed monkey as long as the cannon is aimed directly at the monkey. On the Moon, the force of gravity is only one-sixth as strong as it is on Earth. How should the astronaut aim the cannon to hit the monkey on the Moon?
