An earthquake hits Los Angeles! A wave ripples down the LA Freeway at a speed of 150 mph, with crests 60 m apart. Motorists caught by the quake are shaken up and down inside their cars violently. The road moves so quickly that, after pushing cars up to a peak height at a crest, the asphalt almost leaves the tires behind as they fall into a trough.

Write an equation for this wave of the form


       y(x, t)  =   A  *  sin ( k*x  -  ω*t )
   
but provide the numerical values for all constants, in standard SI units.
