Question

An aircraft travelling at 600 km / h accelerates steadily at 10km / h per second. Taking the speed of sound as 110km / h at the aircraft's altitude, how long will it take to reach the ' sound barrier '?

Answer 1

there is a mistake in the data.         speed of sound = 1100 km/hr

v = u + a t

t = (v - u) / a = (1100 - 600 ) / 10 = 50 hours

speed of sound = 1100 km/hr

v = u + a t

t = (v - u) / a = (1100 - 600 ) / 10 = 50 s

I hope, this will help you
