yulyashka [42]

Answer:

\theta=23.7^{\circ}

Explanation:

The ratio of pressure 2 to 1 us 5.48/1= 5.48 rounded off as 5.5.

Referring to table A.2 of modern compressible flow then M_{\beta_1}=2.2

Also

M_{\beta_1}=M_1 sin \beta and making sin\beta the subject of the formula then

sin\beta=\frac {2.2}{3.5}\\\beta=38.94^{\circ}

Making reference to \theta-\beta-M diagram then

\theta=23.7^{\circ}

LiRa [457]

Answer:

-3044.848m/s^2

Explanation:

Initial velocity = 15.7 m/s (u)

Final velocity = -14.444 m/s (v) velocity after striking moving opposite direction.

Time = 0.0099 s

Average acceleration :

change in velocity/ total time

= V - U/t

= -14.444 m/s - 15.7 m/s/0.0099 s

= -30.144/0.0099 s

= -3044.848m/s^2
