Quizplus · Accepted Answer

The weight of a person is calculated by multiplying their mass by the acceleration due to gravity (9.8 m/s^2). For a 100 kg person, the weight is 100 kg * 9.8 m/s^2 = 980 Newtons. The velocity of the elevator does not affect the calculation of weight since weight is a measure of force due to gravity, not dependent on velocity.
