## Homework Statement

You hear the sonic boom of a high-speed jet plane exactly 4.50 s after it passes directly overhead in level flight. At the time you hear the boom, you see the plane at an angle of 16.0 o above the horizon. Assume that the speed of sound at the altitude of the plane is 325 m/s.

How fast is the plane traveling?

What is the altitude of the plane?

## Homework Equations

v(plane)=velocity of sound/sin(alpha)

But I don't know the equation to find altitude.

## The Attempt at a Solution

I know how to get the first question:

325/sin(16)=1179.1 m/s -->which LONCAPA says is right.

What I don't know is how to get the second part. How do you find the altitude based off of the information given?
