Aperson who has a weight of 165 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 0.72 "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. once the person reaches mars, what is the mass, in units of kilograms [kg], and weight in units of pound-force [lbf], of the person on mars? the gravity of mars is 3.71 meters per second squared [m/s2].
