1. The eye of a hurricane passes over Grand Bahama Island in a direction 60.0
◦ north of
west with a speed of 41.0 km/h. Three hours later the course of the hurricane suddenly
shifts due north, and its speed slows to 25.0 km/h. How far from Grand Bahama is
the hurricane 4.50 h after it passes over the island?

2. Two vectors ˙a and ˙b have equal magnitudes of 4 units. They are oriented as shown in the figure below and their vector sum is ˙r.  Find

a. the x and y components of ˙r,

b. the magnitude of ˙r, and

c. the angle ˙r makes with the positive x-axis.
