(5) A spider hangs from a strand of silk whose radius is 3.28E-6 m. The density of the silk is 1270 kg/m3, when the spider moves, waves travel along the strand of silk at a speed of 293 m/s. Determine the mass of the spider. (Note: The weight of the silk is negligible compared to the tension, so assume tension is constant.) :] mes one 0 a (6) Sidhu uses a 2.09 m long rope to pull Aarna (m = 50.7 kg) horizontally across the floor with a coefcient of kinetic friction of uk = 0.200 at a constant speed of 2.36 m/s. Aarna signals to Sidhu to stop by "plucking" the rope, sending a wave pulse forward along the rope. The pulse reaches Sidhu 565.0 ms later. What is the mass of the rope.7 :] one
