A girl is riding her bicycle. When she gets to a corner, she stops to get a drink from her water bottle. At that time, a friend passes by her, traveling at a constant speed of 8.0 m/s.
a) After 20 s, the girl gets back on her bike and travels with a constant acceleration of 2.2 m/s2. How long does it take for her to catch up with her friend?
b) If the girl had been on her bike and rolling along at a speed of 1.2 m/s when her friend passed, what constant acceleration would she need to catch up with her friend in the same amount of time?
