Geometry Challenge: Catch a Fly Ball on an Airless Planet

[GCT]

Once again, send answers with explanation through private message or email GeneralChemsitryTutor@hotmail.com.

We are playing baseball on an airless planet. A fly ball is hit directly towards an outfielder. The fielder can detect the changing angle that the ball makes with the horizon, but cannot directly judge changes in distance (apparent size of the ball), and there is no apparent lateral motion. How does she decide whether to move forward or backward to catch the ball?

Hey, that's fairly simple..
The player just has to move laterally and he'll see the direction of the ball (eg. foward or backwards)

Btw GeneralChemTutor, something's wrong with the email you posted. Hotmail says it doesn't exist, that's why I posted the answer here..
