To develop this problem we will apply the considerations made through the concept of Doppler effect. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other. At first the source is moving towards the observer. Than the perceived frequency at first
Where F is the actual frequency and v is the velocity of the ambulance
Now the source is moving away from the observer.
We are also so told the perceived frequency decreases by 11.9%
Equating,
Solving for V,
Answer:
Ok so there are many ways to go at this.
you can get a zip lock bag and put a bunch of plastic around the egg inside the bag. (image down below)
Just anything to slow down the descent speed.
Cushion the egg so that something other than the egg itself absorbs the impact of landing.
