Brake or turn? The figure depicts an overhead view of a car's path as the car travels toward a wall. Assume that the driver begins to
brake the car when the distance to the wall is d = 109 m, and take the car's mass as m = 1410 kg, its initial speed as v₁ = 38.0 m/s, and
the coefficient of static friction as µ = 0.530. Assume that the car's weight is distributed evenly on the four wheels, even during
braking. (a) What magnitude of frictional force is needed (between tires and road) to stop the car just as it reaches the wall? (b) What is
the maximum possible static friction fs, max? (c) If the coefficient of kinetic friction between the (sliding) tires and the road is µk = 0.440,
at what speed will the car hit the wall? To avoid the crash, a driver could elect to turn the car so that it just barely misses the wall, as
shown in the figure. (d) What magnitude of frictional force would be required to keep the car in a circular path of radius d and at the
given speed vo?

A typical jar that has been tightened to a reasonable degree requires 2.0 N⋅mN⋅m to open. f you grab a 8.2-cmcm-diameter jar lid with one hand so that your thumb and fingers exert equal magnitude forces on opposite sides of the lid, as in the figure, what is the magnitude of each of the forces?
Biologists have studied the running ability of the northern quoll, a marsupial indigenous to Australia. In one set of experiments, they studied the maximum speed that quolls could run around a curved path without slipping. One quoll was running at 2.8 m/s around a curve with a radius of 1.2 m when it started to slip. What was the coefficient of static friction between the quoll’s feet and the ground in this trial?
