Question

An aircraft travelling 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?​

Answer 1

speed of sound is the final velocity
`v=1100`

and initial velocity $u=600$ , $a=10$

$v=u+at$

$t=\dfrac{v-u}{a}= \dfrac{500}{10}$

$\implies t=50 h$
