Walker, Halliday & Resnick β Kinetic Energy and Work: Problem 17
17 A military helicopter lifts a 75 kg flood survivor 16 m vertically from the river by a rope. If the acceleration of the survivor is g/10, how much work is done on the survivor by (a) the force from the helicopter and (b) the gravitational force on her? Just before she reaches the helicopter, what are her (c) kinetic energy and (d) speed?
π Solution Approach
Given: 17 A, 75 kg, 16 m
