A Tracking Station Lies At The Origin Of A
Coordinate System With The X-axis Due East,
The Y-axis Due North And The Z-axis Vertically
Upwards. Two Aircraft Have Coordinates
(20,25,11) And (26,31,12) Relative To The
Tracking Station.
A Find The Distance Between The Two
Aircraft At This Time.
B The Radar At The Tracking Station Has A
Range Of 40 Km. Determine Whether It
Will Be Able To Detect Both Aircraft.

Jawaban: #1:

Jawaban:

a. dist = √[(26-20)²+(31-25)²+(12-11)²]

= √(36+36+1)

= √73

b. dist 1st aircraft from O

= √(20²+25²+11²)

= √1146

≈ 34 km

34 < 40 ==> within radar

dist 2nd aircraft from O

= √(26²+31²+12²)

= √1781

≈ 42 km

42 > 40 ==> outside radar
