Problem: A child is playing with a hockey stick by poking it to the ice surface. Assuming that the coefficient of static friction between the stick and ice is 0.400,
Part A: What is the maximum angle between the stick and the vertical before the stick starts to slide?
I need help to find the maximum angle between the stick and the vertical before the stick starts to slide.
