In 1992, Akira Matsushima, from Japan, rode a unicycle across the United States, covering about 4,800 km in six weeks. Suppose that, during that trip, he had to find his way through a city with plenty of one-way streets. In the city center, Matsushima had to travel in sequence 280 m north, 220 m east, 350 m north, 360 m west, 120 m south, 60.0 m east, 40.0 m south, 90.0 m west (road construction), and then 70.0 m north. At that point, he stopped to rest. Meanwhile, a curious crow decided to fly the distance from his starting point to the rest location directly ("as the crow flies"). It took the crow 42.0 s to cover that distance. Assuming the velocity of the crow was constant, find its magnitude and direction. west of north. m/s at
