Problem: A 53.0 kg ice skater is gliding along the ice, heading due north at 4.20 m/s . The ice has a small coefficient of static friction, to prevent the skater from slipping sideways, but exttip{mu _{ m k}}{mu_k} =0. Suddenly, a wind from the northeast exerts a force of 4.10 N on the skater.Use work and energy to find the skaters speed after gliding 100 m in this wind.What is the minimum value of exttip{mu _{ m s}}{mu_s} that allows her to continue moving straight north?

A 53.0 kg ice skater is gliding along the ice, heading due north at 4.20 m/s . The ice has a small coefficient of static friction, to prevent the skater from slipping sideways, but =0. Suddenly, a wind from the northeast exerts a force of 4.10 N on the skater.

Use work and energy to find the skaters speed after gliding 100 m in this wind.

What is the minimum value of that allows her to continue moving straight north?
