I. A boy uses a rope to pull a loaded sled of mass m = 125 kg along a horizontal surface of snow at aconstant acceleration a start from rest. The coefficient of kinetic friction μ between the runners andthe snow is 0.10, and the angle o equals to 30°. If in 5.0 seconds, the sled reaches a horizontalvelocity of 2.5 m/s, find out a) the tension T in the rope, b) the work done by the boy on the sled, c)the kinetic energy change of the sled. d) Is the work-energy theorem held in this case? Why or whynot?

(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.
