Explanation:

u = 0 m/s

a = 9.8 m/s²

t = 5s

s

= ut + 1/2at²

= 0 × 1 + 1/2 × 98/10 × 5 × 5

= 49/2 × 5

= 122.5 m

Answer:

Given,

speed of sound in air = 350 m/s

time = 5 secs

By using speed formula,

speed = distance/time

=> distance/time = speed

=> distance = speed * time

=> distance = 350/5

=> distance = 70m

Therefore, the height of the bridge was 70 m
