A testing site includes a machine~made hill covered in a new kind of artificial powder that mimics snow but can exist at temperatures far above freezing. A skier is waiting her turn to ski downhill. She is motionless because her skis are held in place by frictio n. The friction keeping her from sliding downh"i has reached its limit Ge, its highest magnitude). The angle 9 of the hill is 7.5 (as shown above). The mass of the skier and her equipment is 60.0 kg. To two signicant figures, v..'1at is the coefficient of friction? Hint: What kind of friction is acting on the skis and which way is it pointing? Q 0.21 O 0.10 O 0.13 O 0.12 O 0.16 Q 0.18
