a person moves 15 km in north direction and then turns towards northeast and moves 10 km.find out the actual displacement ?
north 15 + 10 cos 45 = 22.07
east 10 sin 45 = 7.07
magnitude = sqrt (22.07^2+7.07^2)
tan compass angle = 7.07/22.07
east 10 sin 45 = 7.07
magnitude = sqrt (22.07^2+7.07^2)
tan compass angle = 7.07/22.07
