Question
A person who has a weight of 158 pound-force [lb; on Earth is travelling to Mars in a spacecraft. As long as the engines on the spacecraft are not operating, the person is essentially weightless
during the voyage. During a course correction, the spacecraft undergoes an acceleration of 0.81 g. The tem "g" is the Earth-normal gravity, so 1 "g" is 9.8 meters per second squared [m's1. This
acceleration makes it feel like there is gravity in the spacecraft, and the person will have a perceived weight during the acceleration period, rather than feeling weightless.
Once the person reaches Mars, what is the mass, in units of kilograms [kg), and weight, in units of pound-force [lb], of the person on Mars? The gravity of Mars is 3.71 meters per second squared
[mis").
