4PRACTICE PROBLEM
A 65 kg geologist on Mars is stranded 18 m away from her rover after a rock slide. Due to the steepness, she is unable to climb. She uses her 1800 W laser, which has 3.0 h of battery life, to generate thrust by firing it downwards, lifting herself out. She has an 18 h supply of oxygen. How long will it take her to reach the rover?
