A ship leaves port at noon at a bearing of 143°.  The ship’s average rate of speed over this time is 12 miles per hour.

Describe the location of the ship at 4:30 p.m. by writing a vector in component form. Then explain what these components mean in terms of the scenario.

 

The component form of the vector representing the ship at 4:30 p.m. is approximately  ⟨_____, _____⟩. This means that the ship is about ____ miles to the ____ and about___ miles to the ____ of where the ship left port. 

 

fill in the blank options:

-41.3, -32.5, -3.6, -2.7, 2.7, 3.6, 32.5, 41.3, north, south, east, west

12 m/hr x  4.5 hr = 54 miles

 

x = 54 cos 143 =......          west  

y = 54 sin 143 = ......          north            assuming 0o is North   ( I think the |41.3|  answer choices above  should be 43.1)
