Flying Circus of Physics In the figure, a 42 kg rock climber is climbing a "chimney" between two rock slabs. The coefficient of static friction between her shoes and the rock is 1.07; between her back and the rock it is 0.931. She has reduced her push against the rock until her back and her shoes are on the verge of slipping. (a) What is the magnitude of each of her forces of push against the two columns of rock? (b) What fraction of her weight is supported by the frictional force on her shoes?
