Conflicting velocity variable names in code accompanying Figure 2.5

[Tomas Junnonen]

Under Figure 2.5 is the following code:

float speed = v.mag();
float dragMagnitude = c * speed * speed;
PVector drag = velocity.get();

The first line should read "float speed = velocity.mag();" in order to be consistent with the last line of the above quoted code. This also makes it consistent with the code repeated in Example 2.5.

Fixed, thank you!
