While Yolanda was parked at her back steps, a slug climbed onto the wheel of her go-cart just above where the wheel makes contact with the ground. When Yolanda hopped in and started to pull away, she did not notice the slug until her wheels had rotated 2 times. Yolanda's wheels have a 12 cm radius.
a. How far off the ground is the slug when Yolanda notices it?
b. How far horizontally has the slug moved?
