.

Centripetal acceleration is


    a = v%5E2%2FR,


where v is the uniform linear speed and R is the radius of the circular track.


Substitute your values 


    140 mph = 1.609*140 = 225.26 km/h = %28225.26%2A1000%29%2F3600 = 62.57 m/s  

and

    R = 1.609*1500 = 2413.5 m, 


and calculate.

Happy calculations (!)
