P6.2-3) A RWD 2011 Corvette Coupe's technical specifications are listed below Assuming that the air drag is constant, applied at the center of mass, and equal to 100 lb and the rolling resistance coefficient is f 0014, what is the cars maximum acceleration on level ground and driving uphill on a road with a 10% grade? Estimate the friction characteristics as that between rubber and dry asphalt and note that the total rolling resistance is equal...
QUESTION 3 The 1500-kg rear driving truck reaches a speed of 50 km/h from rest in a distance of 60 m up the 10-percent incline with constant acceleration. Calculate the normal force under each pair of wheels and the effective coefficient of friction between the tires and the road during this motion (Hints: the driving force from the friction of the rear wheels, not from front wheels).

The car shown has a mass of m=1000 kg and a center of mass located at G. The coefficient of static friction between the wheels and the road is μs=0.250. The dimensions are a=1.15 m, b=1.55 m, and c=0.290 m. Assume the car starts from rest, the wheels do not slip on the road, and that the car experiences constant acceleration. Neglect the mass of the wheels. Part A - Shortest Time to Reach a Given Speed with Rear-Wheel Drive...
4. The car has mass of 2600 kg and center of mass at G. It has front wheel drive and the front wheels at A are slipping. The back wheels at B are free to rotate. Neglect the mass of the wheels.
