rain is falling at 5m/s making 30 degrees with the vertical towards east . to a man walking at 3m/s on a horizontal road towards east , the rain appears to be at a speed of

  • physics -

    All angles are measured CCW from due East.

    Vr = 3 + 5[300o].
    Vr = 3 + 5*cos300+5*sin300 = 3 + 2.5 - 4.33i = 5.5 - 4.33i = 7m/s[322o] = Velocity of the rain.

    322o CCW = 38o S. of E.
