Q. A 62 kg person on skis starts from rest down a hill sloped at 40° from the horizontal. The coefficient of friction between the skis and the snow is 0.10. After the skier had been moving for 5s, the friction of the snow suddenly improved and made net force on the skier zero. What is the new coefficient of friction?
