Question

As it passes over Grand Bahama Island, the eye of a hurricane is moving in a direction 57.0

As it passes over Grand Bahama Island, the eye of a hurricane is moving in a direction 57.0 degree north of west with a speed of 40.4 km/h. (Let i hat bold represent east and j hat bold represent north.) What is the unit-vector expression for the velocity of the hurricane? It maintains this velocity for 3.40h, at which time the course of the hurricane suddenly shifts due north, and its speed slows to a constant 23.0 km.h. This new velocity is maintained for 1.50h. What is the unit-vector expression for the new velocity of the hurricane? What is the unit-vector expression for the displacement of the hurricane during the first 3.40 h? What is the unit-vector expression for the new velocity of the hurricane? What is the unit-vector expression for the displacement of the hurricane during the latter 1.50 h? How far from Grand Bahama is the eye 4.90 h after it passes over the island?
