An older Rolls Royce Ghost is traveling at 25 mph on a roadway with good, dry pavement.The car has a C D = 0.32, 35 ft 2 of frontal area, and weighs 5,445 lb. The wheelbase is 129.7 inand the center of gravity is 25 in above the pavement and 60 in behind the front axle. Thevehicle is traveling on pavement at sea level. The engine produces a hefty 620 ft-lb of torqueand is in a gear of the transmission that provides a gear reduction of 5 to 1 with a 22 in wheelradius and 95% drivetrain mechanical efficiency. If the limo driver needs to accelerate hard inthe Ghost to avoid an accident, what would the acceleration be since it is a rear-wheel drive car?
