A light-rail commuter train blows its 200 Hz horn as it approaches a crossing. The speed of sound is 339 m/s. (a) An observer wa
ddd [48]

Answer:

a) 30.82 m/s

b)  183.33 Hz

Explanation:

a)

V = speed of the sound = 339 m/s

v = speed of the train = ?

f' = observed frequency by the observer = 220 Hz

f = actual frequency of the observer = 200 Hz

using the equation

f' = \frac{fV}{V - v}

220 = \frac{(200)(339)}{339 - v}

v =  30.82 m/s

b)

V = speed of the sound = 339 m/s

v = speed of the train = 30.82 m/s

f'' = observed frequency by the observer as train moves away = ?

f = actual frequency of the observer = 200 Hz

using the equation

f'' = \frac{fV}{V + v}

f'' = \frac{(200)(339)}{339 + 30.82}

f'' = 183.33 Hz

The mechanical energy at top =Mechanical energy at bottom

  • Mass=m=54kg
  • Height=h=51m
  • Acceleration due to gravity=g=10m/s^2
  • Velocity=v=2.6m/s

\\ \tt\longmapsto M_{initial}=M_{Final}

  • Final energy at bottom=The kinetic energy

\\ \tt\longmapsto KE=M_{initial}

\\ \tt\longmapsto KE=P.E_{(Top)}+K.E_{(Top)}

\\ \tt\longmapsto K.E=mgh+\dfrac{1}{2}mv^2

\\ \tt\longmapsto K.E=m\left(gh+\dfrac{v^2}{2}\right)

\\ \tt\longmapsto K.E=54\left((10)(51)+\dfrac{2.6^2}{2}\right)

\\ \tt\longmapsto K.E=54\left(510+\dfrac{6.76}{2}\right)

\\ \tt\longmapsto K .E=54(510+3.38)

\\ \tt\longmapsto K.E=54(513.38)

\\ \tt\longmapsto K.E=27722.52J

\\ \tt\longmapsto K.E=27.7KJ
