Given : . A =(6, 30o) and B = (4,0o) . Hence A = 6 cos30 i + 6 sin30 j . = 5.196 i + 3j . B = 4 cos0 i + 4 sin0 j . = 4 i . A +B = 5.196 i + 3j + 4 i . = 9.196 i + 3 j . (b) . Let A = 3 i ; B = 4 cos 45 i + 4 sin45 j = 2.83 i + 2.83 j ; C = - i . Dx = 3 i + 2.83 i -i = 4.43 i . Dy = 2.83 j . Magnitude ofdistance moved is : . D = (Dx)2 + (Dy)2 . = --------- miles . Direction is : . tan = Dy / Dx . = 2.83 / 4.83 . = --------degree . Solve the above. . Hope this helps u!Related Questions
