Answer:
h = 15.34 m
Explanation:
given,
tuning fork vibration = 513 Hz
speed of sound = 343 m/s
frequency after deflection = 489 Hz
the source (the fork) moves away from the observer, its speed increases and hence the apparent frequency decreases
u = 16.92 m/s
height of the building
v² = u² + 2 g s
16.92² = 2 x 9.8 x h
h = 14.61 m
time taken by sound to reach observer
in this time tuning fork has fallen one more now,
h' = 0.7296 m = 0.73 m
total distance
h = 14.61 + 0.73
h = 15.34 m
