Find the angle between velocity vectors A and B, where à = (5.50 m/s)i – (4.30 m/s)j B = (-7.00 m/s)i + (9.00 m/s)j

5. A hiker travels from camp through the forest. The hiker follows 3 trails and becomes lost. The first is 180 m due west. The second one is 210 m in a direction of 35.00 east of south. The third one is 280 m at 30.0° north of east. What are A) the distance and B) direction the hiker need to walk to return to the camp?
