(a) A worker stands a distance d = 0.725 m from the left end of a platform as shown in the figure. The platform is supported by three lines. Find the tension in each line (in N). Assume the platform is uniform, with length L = 2.00 m and mass 28. and the weight of the worker is 690 N. (Due to the nature of this problem, do not use rounded intermediate values-including answers submitted in WebAssign-in your calculations.) N N N 2.00 m- (b) What If? The worker now begins to walk to the right. If each of the lines can support a maximum tension of 750 N, which line fails first? O line 1 O line 2 line 3 At what location does this occur (measured in m from the left end of the platform)? m
