A 52.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 354 N. Then you must reduce your push to 221 N. to keep it moving at a steady 25.0 cm/s. What are the coefficients of static and kinetic friction between the crate and the floor?

Question

A 52.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push
on it, and the crate just begins to move when your force exceeds 354 N. Then you must reduce
your push to 221 N. to keep it moving at a steady 25.0 cm/s. What are the coefficients of static
and kinetic friction between the crate and the floor?

(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.
