Halliday, Resnick & Walker β Kinetic Energy and Work: Problem 17
SSM A helicopter lifts a 72 kg astronaut 15 m vertically from the ocean by means of a cable. The acceleration of the astronaut is g/10. How much work is done on the astronaut 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: 72 kg, 15 m
Find: (a) the force from the helicopter and; (b) the gravitational force on her? Just before she reaches the; (c) kinetic energy and
