A 740 N bear is standing on a metal plank supported by the cable shown in the figure. At the end of the plank hangs a basket weighing 80 N. Assume the plank is uniform, weighs 200 N, is 5.50 m long, and 0 = 60.0°. Goodies (a) When the bear is at x = 1.10 m, find the tension in the cable supporting the plank and the components of the force exerted by the wall on the left end of the plank. (Enter the magnitudes of your answers in N.) T = = = N N N (b) If the cable can withstand a maximum tension of 875 N, what is the maximum distance (in m) the bear can walk before the cable breaks? (Measure this distance from the wall.) m
