An 80.0 kg hiker is trapped on a mountain ledge following a storm. A helicoptar rescuse the hiker by hovering above him and lowering a cable to him. The mass of the cable is 8.00 kg, and its length is 15.0 m. A sling of mass 70.0 kg is attached to the end of the cable. the hiker attaches himself to the sling, and the helicopter then accelerates upward. terrified by hanging from the cable in midair, the hiker tries to singnal the pilot by sending transverse pulses up the cable. a pulse takes 0.250 s to travel the length of the cable. what is the acceleration of the helicopter?

Text Solution

AI Generated Solution

To solve the problem, we need to find the acceleration of the helicopter using the information provided about the hiker, the sling, the cable, and the time it takes for a pulse to travel the length of the cable. ### Step-by-Step Solution: 1. **Identify the Masses:** - Mass of the hiker (m_hiker) = 80.0 kg - Mass of the sling (m_sling) = 70.0 kg - Mass of the cable (m_cable) = 8.00 kg ...
