i wil mark as brainliest for correct answer
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:
Why do we call green plants are producers?How are the producers different
from herbivores?
Initial velocity, u = 600km/h
Final velocity, v = 1100km/h
Acceleration = 10km/h/s=600km/h ^2
From relation,
a= (v−u)/t
t = (v−u)/a
t=(1100−600)/600
=500/600=5/6 hr=50 sec
