A 1200 lb automobile traveling at 35 m.p.h. (51.3 ft/s) is suddenly stopped when the driver slams on the brakes and the car comes to a complete stop in 1.5 seconds.  Assuming the automobile decelerates at a constant rate, determine the force in lbf the brakes supply to stop the car.     Recall that 1 lbf = 32.2 lbm ft/s2.
