2.A hiker used a compass to orient himself as he walked 3.00 km in a direction 50.0° north of west, and then an additional 2.00 km in a direction 20.0° south of west. The trip took 1.25 hours. Calculate the magnitude and direction of the hiker’s velocity of the hiker using vector components .

Answer 1

well, his final position in relation to his starting point is

(-3cos50°-2cos20°,3sin50°-2sin20°) = (-3.808,1.614)

and as usual, velocity = distance/time
