    V1 = 15m/s[45o E of N.] = 45o N. of E.

    V2 = 18m/s[5o N. of E.].

    Vr = 15m/s[45o] + 18m/s[5o].

    Vr = 15*Cos45+15*sin45 + 18*Cos5+18*sin5.

    Vr = (10.61+10.61i) + (17.93+1.57i) = 28.54 + 12.18i.

    Magnitude = sqrt (28.54^2 + 12.18^2) =

    Tan A = Y/X = 12.18/28.54 = 0.42887. A =
