. 9.6 m . 56° Consider the rock climber climbing on a smooth slab, as shown above: • The coefficient of kinetic friction between the climber's rock shoes and the rock is 0.72. The belayer cannot see the climber who is out of sight beyond the edge of the slab. The belayer cannot hear the climber because the wind is blowing very hard. The climber loses his footing and slides down the slab on his feet starting from rest. = 0.72 (a) Using the Newton's 2nd Law equations for (F)ner and (Fy)net, find the acceleration of the climber. [answer: a = 4.2 m/s² down the slab] (b) How long after the climber loses his footing does the belayer realize she needs to catch the climber's fall? [answer: about 2.1 s]
