A person who has a weight of 161 pound-force [lbf] 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 0.68 g. The term "g" is the Earth-normal gravity, so 1 g is 9.8 meters per second squared [m/s2]. 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. What is the person's mass, in units of kilograms [kg], in the spacecraft while travelling to Mars when the engines are not running?

When the engine is running or not running mass of the person will remain the same(of course I am not considering relativistic physics here and considering the speed of spacecraft very less than light speed ). Since Mass of the man is
= (161/9.8)*0.453592
= 7.451868 kg
The mass is very low hence maybe some data is wrong. Also, I don't understand what you have written in the last of your sentence. Kindly elaborate. If any template is there provide it in the comment section I will solve it accordingly
