Answer:
time = 182.68 s
Explanation:
given data
truck approaches = 470 Hz
truck recedes = 400 Hz
position away = 5.0 km
solution
if V is the speed of sound in air and v is the speed to truck
f is the frequency of sound
when truck approach
f1 =
and when truck recede
f2 =
so here we can say
...........1
v = 27.37 m/s
so here 5 km
S = u×t + 0.5 ×a×t² ...........2
5 × 10³ = 27.37 t + 0
t = 182.68 s
