It was a cold rainy evening when Maria decided to end her relationship with Pedro. Pedro, who was shocked and deeply saddened, walked out, and ran at a constant rate of 3 m/s. After a minute, Maria felt guilty and decided to follow Pedro's path with an initial speed of 2 m/s. If she was able to reach Pedro after another minute, (a) what is her speed (m/s) at this time given that she is running at a constant acceleration? (b) What is her constant acceleration (m/s2)
