An athlete pulls box E using an inextensible rope P while being resisted by another inextensible rope S. Let P be the tension force on rope P and S be the tension force on rope S. Consider particle analysis involving only forces P and S. The same athlete now pulls another box E of mass 63kg up an incline. The coefficients of friction between the box and the incline are µş=0.32 and uk=0.22. Consider particle analysis of the instant when P = 635N, 0 = 10° and a = 29°. Use the indicated coordinate axes. P 5. Which of the following is closest to the resultant of the friction force f and normal force N? 636N, 39.2deg CW from -x 422N, 72.3deg CW from -x 422 N, 77.6deg CCW from +x 411N, 77.6deg CW from -x
