An aircraft traveling at $700 k m / h$ acceleration steadily at $10 k m / h$ per second. Taking the speed of sound as $1100 k m / h$ at the aircraft how long will it take to reach the sound barrier?

Solution

$u = 700 k m / h r$
$v = 1100 k m / h r$
$a = 10 k m / s ²$
$v = u + a t$
$1100 = 700 + 10 t$
$t = 40 h r s$
