g A 3,000-lb car is traveling at 10 mi/h on a roadway with level grade covered with hard-packed snow. The aerodynamic resistance is 1.32 . The rolling resistance is 32.99 . The car's engine is producing 293.14 of tractive effort and is in a gear that gives an overall gear reduction ratio of 4.5 to 1. If the driver needs to accelerate quickly to avoid an accident, what would the acceleration be if the car is (a) front-wheel drive with maximum tractive effort of 421.32 , and (b) rear-wheel drive with maximum tractive effort of 257.48
