Problem 9.5
9.5 A 1080-kg car is parked on a sloped street. The figure shows its wheels and the position of
its center of mass. The street is icy, and as a result the coefficient of static friction between
the car's tires and the street surface is μs = 0.2. Determine the steepest slope (in degrees
relative to the horizontal) at which the car could remain in equilibrium if
a. the brakes are applied to both its front and rear wheels;
b. the brakes are applied to the front (lower) wheels only.
