When a 120-lb woman stands on a snow-covered trail, she sinks slightly into the snow because the compressive stress between her ski boots and the snow is larger than the snow can support without crumbling. Her cross-country skis are 65 in. long and wide. After estimating the dimensions of the boot’s sole, calculate the percentage reduction in stress applied to the snow when she is wearing skis instead of boots.
