A particle moving in the wind has a velocity of (17 i - 6j) mph that lasts for 45 min. The wind changes direction affecting the particle velocity. The new velocity is (5i + 18j) mph and lasts for 1.5 h. Calculate the displacement of the particle, giving the result in component form with unit vectors.
