Question
*13-68. The 0.8-Mg car travels over the hill having the
shape of a parabola. If the driver maintains a constant speed
of 9 m/s, determine both the resultant normal force and the
resultant frictional force that all the wheels of the car exert
on the road at the instant it reaches point A. Neglect the size
of the car.
13-69. The 0.8-Mg car travels over the hill having the
shape of a parabola. When the car is at point A, it is traveling
at 9 m/s and increasing its speed at 3 m/s?. Determine both
the resultant normal force and the resultant frictional force
that all the wheels of the car exert on the road at this instant.
Neglect the size of the car.
