Randall D. Knight β Work and Kinetic Energy: Problem 49
A 50 kg ice skater is gliding along the ice, heading due north at 4.0 m/s. The ice has a small coefficient of static friction, to prevent the skater from slipping sideways, but \(\mu_k = 0\). Suddenly, a wind from the northeast exerts a force of 4.0 N on the skater. a. Use work and energy to find the skaterβs speed after gliding 100 m in this wind. b. What is the minimum value of \(\mu_s\) that allows her to continue moving straight north?
