Answer:
(a) The x-component of velocity is 31.55 km/h
(b) The y-component of velocity is 44.92 km/hr
Solution:
As per the solution:
The relative position of ship A relative to ship B is 4.2 km north and 2.7 km east.
Velocity of ship A, 
= 22 km/h towards South = 
Velocity of ship B, 
= 39 km/h Towards North east at an angle of 
= 
Now, the velocity of ship A relative to ship B:
Now,
Answer:
is the process of spreading
