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 in and the center of gravity is 25 in above the pavement and 60 in behind the front axle. The vehicle is traveling on pavement at sea level. The engine produces a hefty 620 ft-lb of torque and is in a gear of the transmission that provides a gear reduction of 5 to 1 with a 22 in wheel radius and 95% drivetrain mechanical efficiency. If the limo driver needs to accelerate hard in the Ghost to avoid an accident, what would the acceleration be since it is a rear-wheel drive car?

Question
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 in
and the center of gravity is 25 in above the pavement and 60 in behind the front axle. The
vehicle is traveling on pavement at sea level. The engine produces a hefty 620 ft-lb of torque
and is in a gear of the transmission that provides a gear reduction of 5 to 1 with a 22 in wheel
radius and 95% drivetrain
the Ghost to avoid an accident, what would the acceleration be since it is a rear-wheel drive car?
