## Speed of Sound and Mac

1. The problem statement, all variables and given/known data
You are hired as the physics consultant for a large movie studio. The producer is way over budget and wants to perform some special effects that will save him money. He decides to shoot the dramatic action boat chase scene with the boats going at 1/4 the speed of what will be seen on film. He quadruples the speed of playback. Explain why or why not this will work.

2. Relevant equations

Mach # = velocity of boat/ speed of sound
Speed of sound = 331 + 0.60*T
T = temperature

3. The attempt at a solution

I don't even know where to begin. I don't think it will work, but maybe if someone could point me in the right direction?

 Recognitions: Homework Help I think the idea is that the sound won't be right. What happens to the frequency of the sounds heard when playback is quadrupled?
