can you change the scenerio and the numbers of this question : Suppose a fire truck is moving toward a stationary observer at 25.0 m/s. The frequency of the siren
on the fire truck is 800 Hz.
a) Calculate the frequency detected by the observer as the fire truck apporaches.
b) Calculate the frequency detected by the observer after the fire truck passess by.
Sure, here's an altered scenario:
Suppose an ambulance is moving toward a stationary observer at 30.0 m/s. The frequency of the siren on the ambulance is 900 Hz.
a) Calculate the frequency detected by the observer as the ambulance approaches.
b) Calculate the frequency detected by the observer after the ambulance passes by.
