An ant travelled along the vector a whose magnitude is 10 meters and direction is 45 degree to horizontal and then moved along vector b whose magnitude is 9 meters and direction is 0 degree with horizontal . Find its displacement

horizontal: 10/√2 + 9 = 16.07

vertical: 10/√2 = 7.07

total: √(16.07^2 + 7.07^2) = 17.56
