Would someone please go over this step by step with this following problem with me? Thanks in advance.
A hammer taps on the end of a 3.90-m-long metal bar at room temperature. A microphone at the other end of the bar picks up two pulses of sound, one that travels through the metal and one that travels through the air. The pulses are separated in time by 11.0 ms.
What is the speed of sound in this metal?

-
Sound travels faster in liquids and non-porous solids than it does in air.
The speed of sound in normal air is 343 m/s.
At this speed the pulse in air reaches the microphone in 11.37 ms, so the pulse through the bar takes 0.37 ms to travel 3.9 m giving a speed of 10540 m/s.
