5. The vector sum of the displacements G d storm and K d new must give the same result as its originally intended displacement o ˆ (120 km)j d = G where east is # i , north is # j. Thus, we write storm new ˆˆ ˆ (100 km)i, i j. dd A B == + GG (a) The equation storm new o d += G readily yields A = –100 km and B = 120 km. The magnitude of G d new is therefore equal to 22 new | | 156 km dA B =+ = G . (b) The direction is tan –1
