Question: In Figure a climber leans out against a vertical ice wall that has negligible friction. Distance a is 0.914 m and distance L is 2.10

In Figure a climber leans out against a vertical ice wall that has negligible friction. Distance a is 0.914 m and distance L is 2.10 m. His center of mass is distance d = 0.940 m from the feet-ground contact point. If he is on the verge of sliding, what is the coefficient of static friction between feet and ground?
