Question

A meteoroid is traveling east through the atmosphere at 18. 3 km/s while descending at a rate of 11.5 km/s. What is its speed, in km/s?

Answer 1

The speed of meteoroid is 21.61 km/s in south-east.

Step-by-step 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

`AC^2=AB^2+BC^2`

`AC^2=(18.3)^3+(11.5)^2`

`AC=√((18.3)^2+(11.5)^2)`

`AC=21.61\ km/s`

Hence, The speed of meteoroid is 21.61 km/s in south-east.
