When a rocket is traveling toward a mountain at 100 m/s, the sound waves from this rocket's engine approach the mountain at speed v. if the rocket doubles its speed to 200 m/s, the sound waves from the engine will now approach the mountain at speed?

The sound will approach the mountain at the same speed, v, irrespective of the speed of the rocket. This is because sound will always travel at the same speed as long as properties of air remain the same.
Therefore, sound will approach the mountain at velocity v in both 100 m/s and 200 m/s of the rocket.

Answer:

The sound waves from the engine will approach the mountains at the same speed, no matter if the speed of the rocket is 100m/s or 200 m/s.

Explanation:

The sound wave is a property of the air, which means that the speed of the object producing sound does not matter to the sound of the waves, that is, they are always going to be the same.

So the sound waves from the engine will approach the mountains at the same speed, no matter if the speed of the rocket is 100m/s or 200 m/s.
