Question

3. The Geeeologist 1602 One end of a nylon rope is tied to a stationary support at the top of a vertical mine shaft 72 m deep. The rope is stretched taut by a 27 kg box of rocks attached at its lower end. The mass of the rope is 1.3 kg. The geologist at the bottom of the mine signals to his colleague at the top by jerking the rope sideways. IMAGES NOTES DISCUSS UNITS STATS HELP PREFERENCES Part Description Answer Save Status A. How long does it take for this signal to reach the top (ignore the tension due to the mass of the rope)?
