Question

5. [5pt] A fly impacts a spider's web and creates a wave pulse that alerts the spider to its presence. The fly impacts the web at point a, with the spider waiting at point c, as shown below. The distance between points a and b is 3.00 cm, the distance between b and c is 10.00 cm, and the distance between d and e is 11.80 cm. The linear mass density of the web is u 9.18106 g/m and the tension in the web is T - 166 103 N ions Calculate the time it takes the wave pulse to reach the spider travelling along path 1. Repeat the calculation for path 2. What is the difference berween pulse arival times? (ans, 4.14 10-1) Note: The spider can use this difference in arrival rime to cdetermine the location of the fly on the web
