A particle travelled 3.9 m north then turned west and travelled 9.5 m in that direction and lastly, travelled 3.9 m south. If instead the particle turned north and travelled 5.7 m for its third displacement and eventuallv turned west again and travelled 6.7 m, find the particle's total displacement during its journey.
If Vx = 7.90 units and Vy = -6.20 units, determine (a)the magnitude and (b)direction of V⃗.
