Problem: Review. As it passes over Grand Bahama Island the eye of a hurricane is moving in a direction 60.08 north of west with a speed of 41.0 km/h. (a) What is the unitvector expression for the velocity of the hurricane? It maintains this velocity for 3.00 h at which time the course of the hurricane suddenly shifts due north and its speed slows to a constant 25.0 km/h. This new velocity is maintained for 1.50 h. (b) What is the unitvector expression for the new velocity of the hurricane? (c) What is the unit-vector expression for the displacement of the hurricane during the first 3.00 h? (d) What is the unit-vector expression for the displacement of the hurricane during the latter 1.50 h? (e) How far from Grand Bahama is the eye 4.50 h after it passes over the island?
