help with physics problems?
The eye of the hurricane passes over Grand Bahama Island in a direction of 60 degrees north of west with a speed of 41 km / h. Three hours later, during the hurricane was moving north at once, and its velocity decreases to 25 km / h. How far from Grand Bahama 4.50 hours the hurricane after it passes through the island? How do you do the problem?
In the first three hours the eye moves 123 km. In the next 1.5 hours 37.5 km moves. You have a triangle where you know two side lengths and the angle between them (NO 60 gr.). Use the cosine rule for triangles in the data. You should get a response from 150 to 160 km.
