You are riding an elevator that is accelerating upward at 2.20 m/s². You have a spring balance that is accurately calibrated in newtons. When you hang a mass of 10.0 kg on the balance, the reading of the balance is A) 120 N. B) 981 N. C) 76.0 N. D) 10.0 N. E) 9.81 N.

Question

The apparent weight is the sum of the gravitational force and the force due to the elevator's acceleration: F = m(g + a) = 10 kg * (9.81 m/s² + 2.20 m/s²) = 120.1 N, approximately 120 N.
