Answer:
The speed of meteoroid is 21.61 km/s in south-east.
Explanation:
Given that,
A meteoroid is traveling through the atmosphere at 18.3 km/s. while descending at a rate of 11.5 km/s it means 11.5 km/s in south.
We need to draw a diagram
Using Pythagorean theorem
[tex]AC^2=AB^2+BC^2[/tex]
[tex]AC^2=(18.3)^3+(11.5)^2[/tex]
[tex]AC=\sqrt{(18.3)^2+(11.5)^2}[/tex]
[tex]AC=21.61\ km/s[/tex]
Hence, The speed of meteoroid is 21.61 km/s in south-east.
