Question

The picture below shows a football player kicking a football. This is known as two dimensional motion. In which direction does the football move?
A) vertical only (y)



B) horizontal only (x)



C) horizontal and vertical (x, y)



D) horizontal, vertical, and side to side (x, y, and z)

Answer 1

You are true, Stokey.  The correct choice is (c).

If you think about it a little bit more, you'll realize that "side to side" is also a horizontal motion.  

Anyway, the question told us that we're only talking about 2 dimensions.  Well, the The measurements in the 2 dimensions are the x and the y .  If there were a z measurement, that would be the 3rd dimension.
