Question

A person who has a weight of 162 pound-force bl 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 0.75 g. The term "g" is the Earth-normal gravity, so 1 g is 9.8 meters per second squared [m/s 1. 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 perceived weight in units of newtons [N] during the course correction (while the engines are running at an acceleration of 0.75 g)?

Explanation / Answer

ANSWER

Now, Mass = 162 pounds = 73.482 kg

Acceleration = 0.75*g =0.75 *9.8 = 7.35 m/s^2

So, Force = Mass * Acceleration

= 73.482 * 7.35

= 540.09 N (ANSWER)
