Question

Un

An aircraft travelling at 600 km/h accelerates steadily at 10 km/h per second. Taking the
speed of sound as 1100 km/h at the aircraft's altitude, how long will it take to reach the
Sound barrier'?​

Answer 1

50 seconds

Step-by-step explanation:

Acceleration = change in velocity / change in time

a = Δv / Δt

10 km/h/s = (1100 km/h − 600 km/h) / t

t = 50 s
