Describe the relationship between a moving objects mass and its kinetic energy

Aball horizontally thrown from a cliff at 8m/s

The horizontal blue line through the middle of the lens is called the optical axis. as the lamp is moved above or below the axis, keeping the horizontal distance to the center of the lens constant, how does the horizontal distance from the lens to the image change?

If you drive 12 miles north and 35 miles east, what is the direct distance between you and your starting point?
