Question:
In Figure a 49 kg rock climber is climbing a "chimney." The coefficient of static friction between her shoes and the rock is 1.2; between her back and the rock is 0.80. She has reduced her push against the rock until her back and her shoes are on the verge of slipping.(a) Draw a free-body diagram of her.(b) What is the magnitude of her push against the rock?(c) What fraction of her weight is supported by the frictional force on hershoes?
