A 1000 kg car and a 2000 kg truck are both driving at the same speed. The both
have tires with the same coefficient of friction. Which of the following
statements about their minimum stopping distances is true?
The truck can stop quicker than the car because it has more mass, and therefore
more friction
They have the same stopping distance, because their acceleration is independent of
their mass.
O It is impossible to know which can stop quicker without knowing their speed
The car can stop quicker than the truck because it has less mass, and therefore less
inertia

(a) What is the maximum frictional force in the knee joint of a person who supports 66.0 kg of her mass on that knee? (b) During strenuous exercise, it is possible to exert forces to the joints that are easily 10 times greater than the weight being supported. What is the maximum force of friction under such conditions? The frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. Increased frictional forces can cause further damage and pam.
