What do you mean by saying that An aircraft t ravelling at 600km/h accelerates steadily at 10km/h per second. Taking the speed of sound as 1100km/h at the aircraft's altitude, how long will it take to reach the 'sound barrier' ?

Expert Answer:

The question means that the aircraft is initially travelling at 600 km/h and then it accelerates. Now, crossing the sound barrier means the aircraft has to attain the speed of sound. Hence, we will take the final speed of the aircraft as speed of sound, i.e, 1100 km/h.
