A person with a mass of 78 kg is riding in an elevator that is accelerating upward at 1.80 m/s².What is the person's apparent weight? (Use g = 9.8 m/s². ) A)900 N B)760 N C)620 N D)960 N

Question

The apparent weight is the normal force exerted by the elevator floor, which is the sum of the gravitational force and the force due to the elevator's acceleration. Apparent weight = m(g + a) = 78 kg * (9.8 m/s² + 1.8 m/s²) = 78 kg * 11.6 m/s² = 904.8 N, which rounds to 900 N.
