3. Hayden and Amy are pushing/pulling a table (150 kg) up a flight of stairs. You can approximate the stairs as a 36.87° ramp. a. If the coefficient of kinetic friction (p.) is 0.3, with what force do these two need to push up the ramp to keep it moving with constant speed? (You can treat them as one force.)

(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 ten 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 pain.
